[PATCH v6 01/13] [media] exynos5-is: Adding media device driver for exynos5
From: Shaik Ameer Basha shaik.am...@samsung.com
This patch adds support for media device for EXYNOS5 SoCs.
The current media device supports the following ips to connect
through the media controller framework.
* MIPI-CSIS
Support interconnection(subdev interface) between devices
* FIMC-LITE
Support capture interface from device(Sensor, MIPI-CSIS) to memory
Support interconnection(subdev interface) between devices
* FIMC-IS
Camera post-processing IP having multiple sub-nodes.
G-Scaler will be added later to the current media device.
The media device creates two kinds of pipelines for connecting
the above mentioned IPs.
The pipeline0 is uses Sensor, MIPI-CSIS and FIMC-LITE which captures
image data and dumps to memory.
Pipeline1 uses FIMC-IS components for doing post-processing
operations on the captured image and give scaled YUV output.

+Samsung EXYNOS5 SoC Camera Subsystem
+
+
+The Exynos5 SoC Camera subsystem comprises of multiple sub-devices
+represented by separate device tree nodes. Currently this includes: FIMC-LITE,
+MIPI CSIS and FIMC-IS.
+
+The sub-device nodes are referenced using phandles in the common 'camera' node
+which also includes common properties of the whole subsystem not really
+specific to any single sub-device, like common camera port pins or the common
+camera bus clocks.
+
+Common 'camera' node
+
+
+Required properties:
+
+- compatible : must be samsung,exynos5250-fimc
+- clocks : list of clock specifiers, corresponding to entries in
+ the clock-names property;
+- clock-names : must contain sclk_bayer entry
+- samsung,csis : list of phandles to the mipi-csis device nodes
+- samsung,fimc-lite: list of phandles to the fimc-lite device nodes
+- samsung,fimc-is : phandle to the fimc-is device node
+
+The pinctrl bindings defined in ../pinctrl/pinctrl-bindings.txt must be used
+to define a required pinctrl state named default.
+
+'parallel-ports' node
+-
+
+This node should contain child 'port' nodes specifying active parallel video
+input ports. It includes camera A, camera B and RGB bay inputs.
+'reg' property in the port nodes specifies the input type:
+ 1 - parallel camport A
+ 2 - parallel camport B
+ 5 - RGB camera bay
+
+3, 4 are for MIPI CSI-2 bus and are already described in samsung-mipi-csis.txt
+
+Image sensor nodes
+--
+
+The sensor device nodes should be added to their control bus controller (e.g.
+I2C0) nodes and linked to a port node in the csis or the parallel-ports node,
+using the common video interfaces bindings, defined in video-interfaces.txt.
+
+Example:
+
+ aliases {
+ fimc-lite0 = fimc_lite_0
+ };
+
+ /* Parallel bus IF sensor */
+ i2c_0: i2c@1386 {
+ s5k6aa: sensor@3c {
+ compatible = samsung,s5k6aafx;
+ reg = 0x3c;
+ vddio-supply = ...;
+
+ clock-frequency = 2400;
+ clocks = ...;
+ clock-names = mclk;
+
+ port {
+ s5k6aa_ep: endpoint {
+ remote-endpoint = fimc0_ep;
+ bus-width = 8;
+ hsync-active = 0;
+ vsync-active = 1;
+ pclk-sample = 1;
+ };
+ };
+ };
+ };
+
+ /* MIPI CSI-2 bus IF sensor */
+ s5c73m3: sensor@1a {
+ compatible = samsung,s5c73m3

[PATCH v6 13/13] V4L: Add driver for s5k4e5 image sensor
This patch adds subdev driver for Samsung S5K4E5 raw image sensor.
Like s5k6a3, it is also another fimc-is firmware controlled
sensor. This minimal sensor driver doesn't do any I2C communications
as its done by ISP firmware. It can be updated if needed to a
regular sensor driver by adding the I2C communication.

+Samsung EXYNOS5 SoC Camera Subsystem
+
+
+The Exynos5 SoC Camera subsystem comprises of multiple sub-devices
+represented by separate device tree nodes. Currently this includes: FIMC-LITE,
+MIPI CSIS and FIMC-IS.
+
+The sub-subdevices are defined as child nodes of the common 'camera' node which
+also includes common properties of the whole subsystem not really specific to
+any single sub-device, like common camera port pins or the CAMCLK clock outputs
+for external image sensors attached to an SoC.
+
+Common 'camera' node
+
+
+Required properties:
+
+- compatible : must be samsung,exynos5-fimc, simple-bus
+- clocks : list of clock specifiers, corresponding to entries in
+ the clock-names property;
+- clock-names : must contain sclk_bayer entry
+- csis : list of phandles to the mipi-csis device nodes
+- fimc-lite: list of phandles to the fimc-lite device nodes
+- fimc-is : phandle to the fimc-is device node
+
+The pinctrl bindings defined in ../pinctrl/pinctrl-bindings.txt must be used
+to define a required pinctrl state named default.
+
+'parallel-ports' node
+-
+
+This node should contain child 'port' nodes specifying active parallel video
+input ports. It includes camera A, camera B, MIPI-CSI2 and RGB bay inputs.
+'reg' property in the port nodes specifies the input type:
+ 1 - parallel camport A
+ 2 - parallel camport B
+ 3 - serial MIPI CSI-2 port 0
+ 4 - serial MIPI CSI-2 port 1
+ 5 - RGB camera bay
+
+3, 4 are already described in samsung-mipi-csis.txt
+
+Image sensor nodes
+--
+
+The sensor device nodes should be added to their control bus controller (e.g.
+I2C0) nodes and linked to a port node in the csis or the parallel-ports node,
+using the common video interfaces bindings, defined in video-interfaces.txt.
+The implementation of this bindings requires clock-frequency property to be
+present in the sensor device nodes.

[PATCH v5 00/13] Exynos5 IS driver
The patch series add support for Exynos5 camera subsystem. It re-uses mipi-csis and fimc-lite from exynos4-is and adds a new media device and fimc-is device drivers for exynos5. The media device supports asynchronos subdev registration for the fimc-is sensors and is tested on top of the patch series from Sylwester for exynos4-is [1]. [1] http://www.mail-archive.com/linux-media@vger.kernel.org/msg64653.html Changes from v4 --- - Addressed all review comments from Sylwester - Added separate PMU node as suggested by Stephen Warren - Added phandle based discovery of subdevs instead of node name Changes from v3 --- - Dropped the RFC tag - Addressed all review comments from Sylwester and Sachin - Removed clock provider for media dev - Added s5k4e5 sensor devicetree binding doc Changes from v2 --- - Added exynos5 media device driver from Shaik to this series - Added ISP pipeline support in media device driver - Based on Sylwester's latest exynos4-is development - Asynchronos registration of sensor subdevs - Made independent IS-sensor support - Add s5k4e5 sensor driver - Addressed review comments from Sylwester, Hans, Andrzej, Sachin Changes from v1 --- - Addressed all review comments from Sylwester - Made sensor subdevs as independent i2c devices - Lots of cleanup - Debugfs support added - Removed PMU global register access Arun Kumar K (12): [media] exynos5-fimc-is: Add Exynos5 FIMC-IS device tree bindings documentation [media] exynos5-fimc-is: Add driver core files [media] exynos5-fimc-is: Add common driver header files [media] exynos5-fimc-is: Add register definition and context header [media] exynos5-fimc-is: Add isp subdev [media] exynos5-fimc-is: Add scaler subdev [media] exynos5-fimc-is: Add sensor interface [media] exynos5-fimc-is: Add the hardware pipeline control [media] exynos5-fimc-is: Add the hardware interface module [media] exynos5-is: Add Kconfig and Makefile V4L: s5k6a3: Change sensor min/max resolutions V4L: Add driver for s5k4e5 image sensor Shaik Ameer Basha (1): [media] exynos5-is: Adding media device driver for exynos5 .../devicetree/bindings/media/exynos5-fimc-is.txt | 47 + .../devicetree/bindings/media/exynos5-mdev.txt | 130 ++ .../devicetree/bindings/media/i2c/s5k4e5.txt | 43 + drivers/media/i2c/Kconfig |8 + drivers/media/i2c/Makefile |1 + drivers/media/i2c/s5k4e5.c | 361 + drivers/media/i2c/s5k6a3.c | 19 +- drivers/media/platform/Kconfig |1 + drivers/media/platform/Makefile|1 + drivers/media/platform/exynos5-is/Kconfig | 20 + drivers/media/platform/exynos5-is/Makefile |7 + drivers/media/platform/exynos5-is/exynos5-mdev.c | 1218 ++ drivers/media/platform/exynos5-is/exynos5-mdev.h | 160 ++ drivers/media/platform/exynos5-is/fimc-is-cmd.h| 187 +++ drivers/media/platform/exynos5-is/fimc-is-core.c | 413 + drivers/media/platform/exynos5-is/fimc-is-core.h | 132 ++ drivers/media/platform/exynos5-is/fimc-is-err.h| 257 +++ .../media/platform/exynos5-is/fimc-is-interface.c | 810 ++ .../media/platform/exynos5-is/fimc-is-interface.h | 125 ++ drivers/media/platform/exynos5-is/fimc-is-isp.c| 534 ++ drivers/media/platform/exynos5-is/fimc-is-isp.h| 90 ++ .../media/platform/exynos5-is/fimc-is-metadata.h | 767 + drivers/media/platform/exynos5-is/fimc-is-param.h | 1159 ++ .../media/platform/exynos5-is/fimc-is-pipeline.c | 1692 .../media/platform/exynos5-is/fimc-is-pipeline.h | 128 ++ drivers/media/platform/exynos5-is/fimc-is-regs.h | 105 ++ drivers/media/platform/exynos5-is/fimc-is-scaler.c | 472 ++ drivers/media/platform/exynos5-is/fimc-is-scaler.h | 106 ++ drivers/media/platform/exynos5-is/fimc-is-sensor.c | 45 + drivers/media/platform/exynos5-is/fimc-is-sensor.h | 65 + drivers/media/platform/exynos5-is/fimc-is.h| 160 ++ 31 files changed, 9255 insertions(+), 8 deletions(-) create mode 100644 Documentation/devicetree/bindings/media/exynos5-fimc-is.txt create mode 100644 Documentation/devicetree/bindings/media/exynos5-mdev.txt create mode 100644 Documentation/devicetree/bindings/media/i2c/s5k4e5.txt create mode 100644 drivers/media/i2c/s5k4e5.c create mode 100644 drivers/media/platform/exynos5-is/Kconfig create mode 100644 drivers/media/platform/exynos5-is/Makefile create mode 100644 drivers/media/platform/exynos5-is/exynos5-mdev.c create mode 100644 drivers/media/platform/exynos5-is/exynos5-mdev.h create mode 100644 drivers/media/platform/exynos5-is/fimc-is-cmd.h create mode 100644 drivers/media/platform/exynos5-is/fimc-is-core.c create mode 100644 drivers/media/platform/exynos5-is/fimc-is-core.h create mode 100644 drivers/media/platform/exynos5
[PATCH v5 08/13] [media] exynos5-fimc-is: Add sensor interface
Some sensors to be used with fimc-is are exclusively controlled
by the fimc-is firmware. This minimal sensor driver provides
the required info for the firmware to configure the sensors
sitting on I2C bus.

[PATCH v5 13/13] V4L: Add driver for s5k4e5 image sensor
This patch adds subdev driver for Samsung S5K4E5 raw image sensor.
Like s5k6a3, it is also another fimc-is firmware controlled
sensor. This minimal sensor driver doesn't do any I2C communications
as its done by ISP firmware. It can be updated if needed to a
regular sensor driver by adding the I2C communication.

+* Samsung S5K4E5 Raw Image Sensor
+
+S5K4E5 is a raw image sensor with maximum resolution of 2560x1920
+pixels. Data transfer is carried out via MIPI CSI-2 port and controls
+via I2C bus.
+
+Required Properties:
+- compatible : must be samsung,s5k4e5
+- reg : I2C device address
+- gpios: reset gpio pin
+- clocks : clock specifier for the clock-names property
+- clock-names : must contain mclk entry
+- svdda-supply : core voltage supply
+- svddio-supply: I/O voltage supply
+
+Optional Properties:
+- clock-frequency : operating frequency for the sensor
+default value will be taken if not provided.
+
+The device node should be added to respective control bus controller
+(e.g. I2C0) nodes and linked to the csis port node, using the common
+video interfaces bindings, defined in video-interfaces.txt.
+
+Example:
+
+ i2c-isp@1313 {
+ s5k4e5@20 {
+ compatible = samsung,s5k4e5;
+ reg = 0x20;
+ gpios = gpx1 2 1;
+ clock-frequency = 2400;
+ clocks = clock 129;
+ clock-names = mclk;
+ svdda-supply = ...;
+ svddio-supply = ...;
+ port {
+ is_s5k4e5_ep: endpoint {
+ data-lanes = 1 2 3 4;
+ remote-endpoint = csis0_ep;
+ };

+Samsung EXYNOS5 SoC Camera Subsystem
+
+
+The Exynos5 SoC Camera subsystem comprises of multiple sub-devices
+represented by separate device tree nodes. Currently this includes: FIMC-LITE,
+MIPI CSIS and FIMC-IS.
+
+The sub-subdevices are defined as child nodes of the common 'camera' node which
+also includes common properties of the whole subsystem not really specific to
+any single sub-device, like common camera port pins or the CAMCLK clock outputs
+for external image sensors attached to an SoC.
+
+Common 'camera' node
+
+
+Required properties:
+
+- compatible : must be samsung,exynos5-fimc, simple-bus
+- clocks : list of clock specifiers, corresponding to entries in
+ the clock-names property;
+- clock-names : must contain sclk_bayer entry and matching clock property
+ entry
+
+The pinctrl bindings defined in ../pinctrl/pinctrl-bindings.txt must be used
+to define a required pinctrl state named default and optional pinctrl states:
+idle, active-a, active-b. These optional states can be used to switch the
+camera port pinmux at runtime. The idle state should configure both the
camera
+ports A and B into high impedance state, especially the CAMCLK clock output
+should be inactive. For the active-a state the camera port A must be
activated
+and the port B deactivated and for the state active-b it should be the other
+way around.
+
+The 'camera' node must include at least one 'fimc-lite' child node.
+
+'parallel-ports' node
+-
+
+This node should contain child 'port' nodes specifying active parallel video
+input ports. It includes camera A and camera B inputs. 'reg' property in the
+port nodes specifies data input - 0, 1 indicates input A, B respectively.
+
+Image sensor nodes
+--
+
+The sensor device nodes should be added to their control bus controller (e.g.
+I2C0) nodes and linked to a port node in the csis or the parallel-ports node,
+using the common video interfaces bindings, defined in video-interfaces.txt.
+The implementation of this bindings requires clock-frequency property to be
+present in the sensor device nodes.
+
+Example:
+
+ aliases {
+ fimc-lite0 = fimc_lite_0
+ };
+
+ /* Parallel bus IF sensor */
+ i2c_0: i2c@1386 {
+ s5k6aa: sensor@3c {

+ reg = 0x3c;
+ vddio-supply = ...;
+
+ clock-frequency = 2400;

[PATCH v4 00/13] Exynos5 IS driver
The patch series add support for Exynos5 camera subsystem. It re-uses mipi-csis and fimc-lite from exynos4-is and adds a new media device and fimc-is device drivers for exynos5. The media device supports asynchronos subdev registration for the fimc-is sensors and is based on the patch series from Sylwester for exynos4-is [1].

[PATCH v4 08/13] [media] exynos5-fimc-is: Add sensor interface
Some sensors to be used with fimc-is are exclusively controlled
by the fimc-is firmware. This minimal sensor driver provides
the required info for the firmware to configure the sensors
sitting on I2C bus.

[PATCH v4 09/13] [media] exynos5-fimc-is: Add the hardware pipeline control
This patch adds the crucial hardware pipeline control for the
fimc-is driver. All the subdev nodes will call this pipeline
interfaces to reach the hardware. Responsibilities of this module
involves configuring and maintaining the hardware pipeline involving
multiple sub-ips like ISP, DRC, Scalers, ODC, 3DNR, FD etc.

[PATCH v4 13/13] V4L: Add driver for s5k4e5 image sensor
This patch adds subdev driver for Samsung S5K4E5 raw image sensor.
Like s5k6a3, it is also another fimc-is firmware controlled
sensor. This minimal sensor driver doesn't do any I2C communications
as its done by ISP firmware. It can be updated if needed to a
regular sensor driver by adding the I2C communication.

+* Samsung S5K4E5 Raw Image Sensor
+
+S5K4E5 is a raw image sensor with maximum resolution of 2560x1920
+pixels. Data transfer is carried out via MIPI-CSI2 port and controls
+via I2C bus.
+
+Required Properties:
+- compatible : must be samsung,s5k4e5
+- reg : I2C device address
+- gpios: reset gpio pin
+- clocks : clock specifier for the clock-names property.
+- clock-names : must contain mclk entry and matching clock property
+ entry.
+- svdda-supply : core voltage supply
+- svddio-supply: I/O voltage supply
+
+Optional Properties:
+- clock-frequency : operating frequency for the sensor
+default value will be taken if not provided.
+
+The device node should be added to their control bus controller (e.g.
+I2C0) nodes and linked to the csis port node, using the common video
+interfaces bindings, defined in video-interfaces.txt.
+
+Example:
+
+ i2c-isp@1313 {
+ s5k4e5@20 {
+ compatible = samsung,s5k4e5;
+ reg = 0x20;
+ gpios = gpx1 2 1;

[PATCH] [media] exynos-gsc: fix s2r functionality
From: Prathyush K prathyus...@samsung.com
When gsc is in runtime suspended state, there is no need to call
m2m_suspend during suspend and similarily, there is no need to call
m2m_resume during resume if already in runtime suspended state. This
patch adds the necessary conditions to achieve this.

Hi Sylwester,
Thank you for the review.

+ /*

It's a bit mysterious to me, is this requirement still valid on Exynos5 ?
I glanced over the Exynos5250 datasheet and there seem to be no sclk_cam?
clocks dependency on any of GScaler clocks. Maybe you don't need a clock
provider in this driver, perhaps sensor drivers could use sclk_cam clocks
directly, assigned through dts ?
Yes these clocks can be directly exposed via dt.
I will drop clock provider from this driver.

+ continue;
+ clk_put(fmd-camclk[i].clock);
+ fmd-camclk[i].clock = ERR_PTR(-EINVAL);
+ }
Please double check if you need this sclk_cam clocks handling. We could
simply add a requirement that this driver supports only sensor subdevs
through the v4l2-async API and which controls their clock themselves.
sclk_cam* handling can be removed and be done from respective
sensors. But I think the sclk_bayer handling needs to be retained in the
media driver.

Could you explain a bit how is this SCLK_BAYER clock used ? Is it routed
to external image sensor, or is it used only inside an SoC ?
It is not defined properly in the manual, but I suppose its the bus clock
for the bayer rgb data bus. So for proper sensor functionality, we need this
sclk_bayer in addition to the external sensor clks (sclk_cam*). Isn't
exynos5 media driver is the best place to handle such clocks?

So all those floating point numbers are now not really used in

Yes. Same floats are used in firmware internal data structures
also and the driver should assign these values when these parameters

[RFC v3 01/13] [media] exynos5-is: Adding media device driver for exynos5
From: Shaik Ameer Basha shaik.am...@samsung.com
This patch adds support for media device for EXYNOS5 SoCs.
The current media device supports the following ips to connect
through the media controller framework.
* MIPI-CSIS
Support interconnection(subdev interface) between devices
* FIMC-LITE
Support capture interface from device(Sensor, MIPI-CSIS) to memory
Support interconnection(subdev interface) between devices
* FIMC-IS
Camera post-processing IP having multiple sub-nodes.
G-Scaler will be added later to the current media device.
The media device creates two kinds of pipelines for connecting
the above mentioned IPs.
The pipeline0 is uses Sensor, MIPI-CSIS and FIMC-LITE which captures
image data and dumps to memory.
Pipeline1 uses FIMC-IS components for doing post-processing
operations on the captured image and give scaled YUV output.

+Samsung EXYNOS5 SoC Camera Subsystem (FIMC)
+--
+
+The Exynos5 SoC Camera subsystem comprises of multiple sub-devices
+represented by separate device tree nodes. Currently this includes: FIMC-LITE,
+MIPI CSIS and FIMC-IS.
+
+The sub-subdevices are defined as child nodes of the common 'camera' node which
+also includes common properties of the whole subsystem not really specific to
+any single sub-device, like common camera port pins or the CAMCLK clock outputs
+for external image sensors attached to an SoC.
+
+Common 'camera' node
+
+
+Required properties:
+
+- compatible : must be samsung,exynos5-fimc, simple-bus
+- clocks : list of clock specifiers, corresponding to entries in
+ the clock-names property;
+- clock-names : must contain sclk_cam0, sclk_cam1 entries,
+ matching entries in the clocks property.
+
+The pinctrl bindings defined in ../pinctrl/pinctrl-bindings.txt must be used
+to define a required pinctrl state named default and optional pinctrl states:
+idle, active-a, active-b. These optional states can be used to switch the
+camera port pinmux at runtime. The idle state should configure both the
camera
+ports A and B into high impedance state, especially the CAMCLK clock output
+should be inactive. For the active-a state the camera port A must be
activated
+and the port B deactivated and for the state active-b it should be the other
+way around.
+
+The 'camera' node must include at least one 'fimc-lite' child node.
+
+'parallel-ports' node
+-
+
+This node should contain child 'port' nodes specifying active parallel video
+input ports. It includes camera A and camera B inputs. 'reg' property in the
+port nodes specifies data input - 0, 1 indicates input A, B respectively.
+
+Optional properties
+
+- samsung,camclk-out : specifies clock output for remote sensor,
+ 0 - CAM_A_CLKOUT, 1 - CAM_B_CLKOUT;
+
+Image sensor nodes
+--
+
+The sensor device nodes should be added to their control bus controller (e.g.
+I2C0) nodes and linked to a port node in the csis or the parallel-ports node,
+using the common video interfaces bindings, defined in video-interfaces.txt.
+The implementation of this bindings requires clock-frequency property to be
+present in the sensor device nodes.
+
+Example:
+
+ aliases {
+ fimc-lite0 = fimc_lite_0
+ };
+
+ /* Parallel bus IF sensor */
+ i2c_0: i2c@1386 {
+ s5k6aa: sensor@3c {
+ compatible = samsung,s5k6aafx;
+ reg = 0x3c;
+ vddio-supply = ...;
+
+ clock-frequency = 2400;
+ clocks = ...;
+ clock-names = mclk;

[RFC v3 08/13] [media] exynos5-fimc-is: Add sensor interface
Some sensors to be used with fimc-is are exclusively controlled
by the fimc-is firmware. This minimal sensor driver provides
the required info for the firmware to configure the sensors
sitting on I2C bus.

[RFC v3 13/13] V4L: Add driver for s5k4e5 image sensor
This patch adds subdev driver for Samsung S5K4E5 raw image sensor.
Like s5k6a3, it is also another fimc-is firmware controlled
sensor. This minimal sensor driver doesn't do any I2C communications
as its done by ISP firmware. It can be updated if needed to a
regular sensor driver by adding the I2C communication.

Re: [REVIEW PATCH 0/6] exynos4-is: Asynchronous subdev registration support
Hi Sylwester, On Wed, Jul 24, 2013 at 12:09 AM, Sylwester Nawrocki s.nawro...@samsung.com wrote: This patch series is a refactoring of the exynos4-is driver to get rid of the common fimc-is-sensor driver and to adapt it to use standard sensor subdev drivers, one per each image sensor type. Then a clock provider is added to the exynos4-is driver and the s5k6a3 subdev is modified to use one of the clocks registered by exynos4-is. Arun, I think you could reuse the s5k6a3 sensor for your work on the Exynos5 FIMC-IS driver. One advantage of separate sensor drivers is that the power on/off sequences can be written specifically for each sensor. We are probably going to need such sequences per board in future. Also having the clock control inside the sensor subdev allows to better match the hardware power on/off sequence requirements, however the S5K6A3 sensor can have active clock signal on its clock input pin even when all its power supplies are turned off. I'm posting this series before having a proper implementation for clk_unregister() in the clock framework, so you are not blocked with your Exynos5 FIMC-IS works. Thank you for the patches. I am modifying exynos5-is based on the same design.

What would be nice is if the fmic specific parts are replaced by callbacks into the bridge driver using v4l2_subdev_notify(). The platform data (or DT) can also state if this sensor is firmware controlled or not. If not, then the missing bits can be implemented in the future by someone who needs that.

It is currently empty. The media device driver could call s_stream on the ISP subdev each time it sees s_stream request on the sensor subdev. And you wouldn't need any hacks to get the pipeline pointer in the sensor subdev. Then it would be something like: /dev/video? media-dev-driversensor-subdev FIMC-IS-ISP-subdev | | | | | VIDIOC_STREAMON | | | |# s_stream()| | | #--| | | # s_stream()| | | #---+# pipeline_open() | | | # pipeline_start() | | | # I suppose pipeline_open() is better candidate for the s_power callback. It just needs to be ensured at the media device level the subdev operations sequences are correct. It can be done this way. But my intention of putting these calls in the sensor subdev was to use the sensor subdev independent of isp subdev. This is for the usecase where the pipeline will only contain is-sensor -- mipi-csis -- fimc-lite --- memory This way you can capture the bayer rgb data from sensor without using any isp components at all. The second pipeline which is isp -- scc -- scp can be used for processing the sensor data and can be created and used if needed. In the method you mentioned, the isp subdev has to be used even when it is not part of the pipeline. Is that allowed? If its allowed as per media pipeline guidelines, then this definitely is a better approach. Please suggest on this. Sure, I'm aware of those two relatively separate pipelines. s_power, s_stream callbacks belong to the kernel so I don't think it would be an issue to do it as I described. Please note s_power, s_stream are normally reference counted. Alternatively you could create a separate subdev for the FIMC-IS firmware interface. Such subdev wouldn't be exposing device node and would be used by the media pipeline controller driver to ensure proper hardware configuration sequences. I don't know the Exynos5 FIMC-IS firmware architecture very well so I'm not sure if it is worth to create such a separate

These are for the sensor controls (especially clock lines). I think I should move these to the sensor node. This doesn't sound right either. These pins are not a property of an external image sensor device, they are specific to the AP SoC. So IMO these pinctrl properties belong to some SoC's internal device node. Ok. Time being I will move it to the camera node pinctrl properties. I think we could add a clock provider for the sclk_cam clocks and then the pinmux of those clock outputs could be configurable from with the clock ops. E.g. we set the pinumx into CAM_?_CLKOUT function only when a clock is enabled. Disabling a clock would put CLKOUT pin pinmux e.g. into input with pull down state. This would ensure proper CLKOUT pin configuration when image sensor is suspended or entirely powered off. I'm working on something like this for exynos4. Ok that would be great.

If so then it is likely not needed to specify it here right now. But I believe for complete H/W description we should reserve a possibility to add those various peripheral device nodes here. Yes its going to be used by the firmware and is done for sensor calibration. The sensor works well even without it and so I didnt include it in my initial patchset and kept it as a todo. I2C bus is used by the sensor which has its own node. May be I should explain one of the sensor nodes over here? I would describe at least I2C bus controller node and add a note that image sensor nodes can be specified there. I havent created a dummy i2c device driver for handling the i2c clock part and everything was handled in the fimc-is-sensor itself. I was checking your exynos4 implementation and will try to do in similar lines. Also, it would be good to start adding separate sensor drivers for each sensor, like s5k6a3, s5k4e3, etc. Ideally we should not have duplicated fimc-is-sensor.[ch] that would handle various

What's the point of this check ?
Check was added to ensure ISP input width and height is
set same as the sensor output or not.
But yes this cannot be extended to generic (non-IS controlled) sensors.
Will drop this check and let media controller take care.

I meant that you could do the assignment unconditionally, since you
always end up with sensor_width/height assigned to pix_mp.width/height.
Indeed, this should be handled by subdev ioctls, and any discrepancies
should be detected while starting streaming and reported to user space.
Ok I got it. Will modify accordingly
Thanks Regards

[PATCH] [media] exynos4-is: Fix fimc-lite bayer formats
The 10bit and 12bit bayer output formats supported
by fimc-lite actually uses 16bits where the extra
bits are padded with zeros. The patch corrects this
by modifying depth field of these two formats.

Oh, so you enable all clocks in this driver ? Is it really flexible
enough ? What if one of these clocks is connected to some external
sensor with an ISP ? Are this clocks going to be managed/exposed by
the media device driver as well ?
I was hoping that this driver can handle all its clocks as exposed
from the DT. I can see that in exynos4, the media device enables the
cam clocks. In exynos5, there are multiple frequency settings
possible on these clocks depending on modes of operation.
So isn't it better that the sensor driver

Signed-off-by: Arun Kumar K arun...@samsung.com Signed-off-by: Kilyeon Im kilyeon...@samsung.com Not surprisingly I really hate the idea of sensor drivers that are tied to a specific SoC, since it completely destroys the reusability of such drivers. Yes agree to it. I understand that you have little choice to do something special here, but I was wondering whether there is a way of keeping things as generic as possible. I'm just brainstorming here, but as far as I can see this driver is basically a partial sensor driver: it handles the clock, the format negotiation and power management. Any sensor driver needs that. What would be nice is if the fmic specific parts are replaced by callbacks into the bridge driver using v4l2_subdev_notify(). The platform data (or DT) can also state if this sensor is firmware controlled or not. If not, then the missing bits can be implemented in the future by someone who needs that. That way the driver itself remains independent from fimc. And existing sensor drivers can be adapted to be usable with fimc as well by adding support for the notify callback. Would a scheme along those lines work? Yes this should make the implementation very generic. Will check the feasibility of this approach.

Re: [PATCH v3 7/8] [media] V4L: Add VP8 encoder controls
Hi Hans On Fri, Jun 28, 2013 at 7:55 PM, Hans Verkuil hverk...@xs4all.nl wrote: Hi Arun, As promised, here is my review. Thank you :). Sorry for the delay in response. I have been thinking a bit more about whether or not a VPX control class should be added, and in my opinion it shouldn't. These controls should be part of the MPEG control class, as the VPX encoder shares a lot of general encoding parameters, just like h264 and mpeg4. It is unfortunate that all the defines contain the MPEG name, and I take the blame for that since I came up with these defines originally. That said, there are some things that can be done to make it less confusing: - Clearly state in v4l2-controls.h and v4l2-ctrls.c that the MPEG controls are really Codec Controls, so not MPEG specific, and that the 'MPEG' part of the define is historical. Ok will do that. - Currently the V4L2_CID_MPEG_CLASS name in v4l2-ctrls.c is MPEG Encoder Controls. This should be changed to Codec Controls, since the controls in this class are neither MPEG specific, nor are they encoder specific as there are also controls related to the decoder. - Update the DocBook section for the MPEG controls accordingly: change 'MPEG' in the text to 'Codec' and add a note explaining why all the defines are prefixed with V4L2_CID_MPEG/V4L2_MPEG instead of _CODEC. Ok will do these changes. I did toy with the idea of adding aliases in v4l2-controls.h replacing MPEG with CODEC, but that really is too messy. I think if you can take care of the three points mentioned above we should be OK. This also means that in this patch the V4L2_CID_VPX_ prefix changes to V4L2_CID_MPEG_VIDEO_VPX_ as that is consistent with the current naming convention in v4l2-controls.h: V4L2_CID_MPEG_VIDEO_H264_ASO, V4L2_CID_MPEG_VIDEO_MPEG4_LEVEL. Ok. Enums use V4L2_MPEG_VIDEO_VPX_ prefix. Yes, I know, this will make the names quite a bit longer, but it is important for consistency. Codecs are likely to have lots of controls since there are lots of knobs you can tweak. So using a systematic naming scheme will prevent it from descending into chaos...

[PATCH v4 5/8] [media] s5p-mfc: Update driver for v7 firmware
Firmware version v7 is mostly similar to v6 in terms
of hardware specific controls and commands. So the hardware
specific opr_v6 and cmd_v6 are re-used for v7 also. This patch
updates the v6 files to handle v7 version also.

[PATCH v4 2/8] [media] s5p-mfc: Rename IS_MFCV6 macro
The MFC v6 specific code holds good for MFC v7 also as
the v7 version is a superset of v6 and the HW interface
remains more or less similar. This patch renames the macro
IS_MFCV6() to IS_MFCV6_PLUS() so that it can be used
for v7 also.

[PATCH v5 2/8] [media] s5p-mfc: Rename IS_MFCV6 macro
The MFC v6 specific code holds good for MFC v7 also as
the v7 version is a superset of v6 and the HW interface
remains more or less similar. This patch renames the macro
IS_MFCV6() to IS_MFCV6_PLUS() so that it can be used
for v7 also.

[PATCH v5 5/8] [media] s5p-mfc: Update driver for v7 firmware
Firmware version v7 is mostly similar to v6 in terms
of hardware specific controls and commands. So the hardware
specific opr_v6 and cmd_v6 are re-used for v7 also. This patch
updates the v6 files to handle v7 version also.
