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.

Sorry, I missed this previously. How about renaming this file to something
more specific to the subsystem it describes, e.g. exynos5250-camera.txt ?

+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 {
