Add support for dynamically selecting 10 bit and 1920x1080@30 resolutions while leaving the existing configuration as default V8 -> V9 -Updated all array values with samall later to get unifamity in mode array values -corrected hblank_min, hbalank, pix_clk for 1920x1080@30 updated according to link frequency -corrected mutex use for imx334_get_format_code function -corrected the fmt->format.code value assinment -in function imx334_get_format_code variable "i" value comparision corrected V7 -> V8 -patch drop "mimx334-odify-link-frequency" as per the commnets linkfrquncy will be half of the line bandwidth -changed 1920x1080@30 mode link frequency from (891000000Mbps) to (445500000Mbps). linkfrquncy will be half of the line bandwidth V6 -> V7 Reloved: kernel test robot warning "drivers/media/i2c/imx334.c:767:15: warning: unused variable 'i' " V5 -> V6 -Drop the dt-binding patch -Optimize the code to avoid duplicating the lines -Added proper mutex while imx334_mbus_codes array -Modified Function __v4l2_ctrl_modify_range arguments as per the review commants -Added hblank dummy set ctrl -Removed Redundant comment -corrected code alignment -All commit msgs are re-written 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 -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 -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, Shravan Chippa (4): media: i2c: imx334: replace __v4l2_ctrl_s_ctrl to __v4l2_ctrl_modify_range media: i2c: imx334: add missing reset values for mode 3840x2160_regs[] media: i2c: imx334: support lower bandwidth mode media: i2c: imx334: update pixel and link frequency drivers/media/i2c/imx334.c | 339 +++++++++++++++++++++++++++++++++---- 1 file changed, 309 insertions(+), 30 deletions(-)
