[PATCH v12 0/5] media: i2c: imx334: support lower bandwidth mode

[shravan kumar]

From: Shravan Chippa <shravan.chippa at microchip.com>

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 at 60 resolutions.

Add support for dynamically selecting 10 bit and 1920x1080 at 30
resolutions.

V11 -> V12
Update default link frequency from device tree max link
frequency value.
Update init_cfg() function to update the link frequency
menu_skip_mask value.

V10 -> V11
Changed veriable type int to unsigned int
Updated CC list

V10 -> V10
PATCH RESEND with updated CC list

V9 -> V10
Added new dt-binding patch
added support for handling multiple link-frequncy
minor changes on coding style

V8 -> V9
-Updated all array values with samall later to get unifamity
in mode array values
-corrected hblank_min, hbalank, pix_clk for 1920x1080 at 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 at 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 at 60 as per the mode
values
-Updated 1782000000Mbps link frequency in dt-bindings also
-Updated 3840x2160 at 60 mode array with default(reset) values

-Updated hblank __v4l2_ctrl_s_ctrl() to __v4l2_ctrl_modify_range()
Suggested-by: Jacopo Mondi <jacopo at 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 at 30 mode

-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: 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
  dt-bindings: media: i2c: imx334 add new link_freq
  media: i2c: imx334: update pixel and link frequency
