Hi

This patch series is for imx334 sensor driver support for lower bandwidth

Some platforms may not be capable of supporting the bandwidth
required for 12 bit or 3840x2160@60 resolutions.

Add support for dynamically selecting 10 bit and 1920x1080@30
resolutions while leaving the existing configuration as default

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 <jacopo@jmondi.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@iki.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[]


Shravan Chippa (5):
  media: i2c: imx334: modify link frequency as for the configureation
  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
