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
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 <[email protected]>
-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 <[email protected]>
-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

From: Shravan Chippa <[email protected]>
-If we have only one mode there is no need to update camera
reset(default) values when we initialize the camera
-If we have mutipull modes in this case we need all value to
write while camera initializing, so i will not effect other modes
while shifting dynamically
-All default values for 3840x2160@60 updated becouse if we change
the mode we will not be able to recover the values, so add in
mode_3840x2160_regs[] array

-Imx334 camera is configured for 1782Mbps/lane for 3840x2160@60
resolution. but the imx334_parse_hw_config() function comparing with
IMX334_LINK_FREQ(891Mbpa/lane) link frequency
-The 3840x2160@60 mode values for 1782Mbps/lane
-Updated Macro IMX334_LINK_FREQ to 1782Mbps/lane
-The same value is populated in the userspce also

-imx334 sensor is configured to 1782Mbps/lane for 3840x2160@60.
-But in device tree bindings exapmple we are passing 891Mbps/lane
so modified to 1782Mbps

My understanding is that the original frequency is correct --- 594 MHz
pixel clock, 12 bpp, four lanes (and DDR).

You could use >= instead, as you do below. You could also refactor this a

Please remove dashes in front of the paragrahs and use period in the end of
sentences.
Are these registers' values specific to this mode or are they different on
different modes?

Yes, These are different for different mods
default values are matching with 3840x2160@60 mode
if we change mode dynamically we need to take care. so added.

As per my understanding, other than these three parameters there is
one more link frequency (communication frequency from imx334 sensor to
MIPI CSI2 controller).
