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
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@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 <jacopo@xxxxxxxxxx>
-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@xxxxxx>
-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
