Add support for dynamically selecting 10 bit and 1920x1080@30 resolutions while leaving the existing configuration as default Sorry for taking dealy to send updated the series as i need to check the impact of my patch on 3840x2160@60 resolutions V4 -> V5 -Added 5 more patchs as per the review comments witch has below updates -Updated 1782000000Mbps link frequency for 3840x2160@60 as per the mode values -Updated 1782000000Mbps link frequency in dt-bindings also -Updated 3840x2160@60 mode array with default(reset) values -Updated hblank __v4l2_ctrl_s_ctrl() to __v4l2_ctrl_modify_range() Suggested-by: Jacopo Mondi <jacopo@...ndi.org> -Current mode update only when we try to set V4L2_SUBDEV_FORMAT_ACTIVE -Added link frequency (891000000Mbps) and pixel rate (74250000) to 1920x1080@30 mode Suggested-by: Sakari Ailus <sakari.ailus@....fi> -Updated commit message V3 -> V4 - Make the 12 bit and 3840x2160 as default - Set bus code SRGGB12 if set format fails V2 -> V3 - Fixed the warning reported by kernel test robot V1 -> V2 - Addressed the review comment given by Jacopo Mondi, Which has bug in imx334_enum_frame_size() loop function, - Renamed array codes[] to imx334_mbus_codes[] - Modified supported_modes[] to get higher resolution first Shravan Chippa (6): dt-bindings: imx334: modify link frequency in examples media: i2c: imx334: modify link frequency as for the configureation media: i2c: imx334: hblank set function modify media: i2c: imx334: add default values in 3840x2160@60 array media: i2c: imx334: support lower bandwidth mode media: i2c: imx334: updating pixel and link frequency .../bindings/media/i2c/sony,imx334.yaml | 2 +- drivers/media/i2c/imx334.c | 338 ++++++++++++++++-- 2 files changed, 311 insertions(+), 29 deletions(-) -- 2.34.1
