The R-Car V3U SoC is capable of capturing RAW10. Add support for it using the V4L2_PIX_FMT_Y10 pixel format, which I think is the correct format to express RAW10 unpacked to users. Signed-off-by: Niklas Söderlund <niklas.soderlund+renesas@ragnatech.se> --- Hi Renesas BSP team, I don't have a RAW10 capable device, could you please test this patch and provide a Tested-by tag?
