This patch adds subdev driver for Samsung S5K6A3 raw image sensor.
As it is intended at the moment to be used only with the Exynos
FIMC-IS (camera ISP) subsystem it is pretty minimal subdev driver.
It doesn't do any I2C communication since the sensor is controlled
by the ISP and its own firmware.
This driver, if needed, can be updated in future into a regular
subdev driver where the main CPU communicates with the sensor
directly.

Where is this used?
This will be called when user process opens the corresponding /dev/v4l-subdev*
device node. More details on the v4l2 sub-device interface can be found at [1],
[2]. The device node is created by an aggregate media device driver, once all
required sub-devices are registered to it.
The above v4l2_subdev_internal_ops::open() implementation is pretty simple,
it just sets V4L2_SUBDEV_FORMAT_TRY format to some initial default value.
That's a per file handle value, so each process opening a set of sub-devices
can try pipeline configuration independently.

Thanks for the explanation. However, I've found no reference to the
s5k6a3_sd_internal_ops struct in the driver code. There surly has to be at
least one reference for the upper layer to access these ops.

Re: [PATCH 1/1] ARM: Exynos: Add generic compatible string
On Tuesday 25 February 2014, Olof Johansson wrote: I disagree. I don't know what Samsung has in mind, but the revision of the CPU doesn't have all that much to do with the rest of the SoC. It's quite likely that some vendors (maybe not Samsung, but the same concept applies) will ship 64-bit SoCs that are very similar to their preceding 32-bit ones, same IP, similar busses, etc. I'm pretty sure at least some vendors will do very close to that. Right. So, if EXYNOS4 and EXYNOS5 can share a compatible value when they use different CPUs, then there's no reason that whatever future 64-bit ones can also share it. How about putting both 'samsung,exynos' and 'samsung,exynos4' in DT then and having the platform code match exynos4 and exynos5 but not exynos? That way, I think we are consistent and future-proof. Any code that needs to know if it's running on some exynos version can just check for the 'samsung,exynos' compatible value and that will work on both arm32 and arm64. Also, if we ever decide we want to run a 32-bit kernel on a 64-bit exynos, we can just add 'samsung,exynos6' (or whatever number that will be) to the list. My usual disclaimer for this: You should never ever consider actually running a 32-bit kernel on a 64-bit CPU, but at the same time there shouldn't be any reason why it won't work either, given that we require arm64 based systems to have all SoC specific code in drivers and we can use the same drivers on arm32.

[PATCH v2 0/2] ARM: SAMSUNG: remove the rest of local uncompress.h files
Two patches from Sachin Kamat already removed the Exynos-uncompress.h . But in fact all Samsung platforms can use the generic uncompress code without needing local implementation. Therefore this two-part series removes the rest of the uncompress.h files from all Samsung platforms. Tested on a s3c2416 and s3c2442 based machine.

[PATCH 0/3] introduce new config option for samsung common clock
This patchset introduces a new config option for Samsung common clock infrastructure as COMMON_CLK_SAMSUNG. As current samsung common clock gets compiled based on PLAT_SAMSUNG, but moving ahead with ARM64 we can not have any more such config options, so better we introduce new COMMON_CLK_SAMSUNG and make it dependent on existing ARCH_ which needs SAMSUNG common clock infrastructure, also on ARM64.
