Another batch of improvements of the imx335 driver.
Patch 1/6 adds support for 2 or 4 lane operation modes.
Patch 2/6 call the V4L2 fwnode device parser to handle controls that are
standardised by the framework.
Patch 3/6 introduces the use of CCI for registers access.
Patch 4/6 uses decimal values for sizes registers (instead of
hexadecimal). This improves overall readability
Patch 5/6 fixes the height value discrepency. Accessible height is 1944,
as per the data sheet
Patch 6/6 fixes the max analogue gain value.
Changes in v6:
- Modify 2/6 to call v4l2_fwnode_device_parse()
early in imx335_init_controls() and return early if error.
- Treat v4l2_ctrl_new_fwnode_properties() as one of framework
functions, hence check ctrl_hdlr->error should be sufficient as
requested.
Changes in v5:
- Simplify error handling in 2/6. Check for ctrl_hdlr->error
- Space fix around { } in 3/6. Drop /* undocumented * as well
Changes in v4:
- Do not change from window cropping mode in patch 4/6.
In v3, the sensor was changed to all pixel scan mode to
achieve height=1944, but it can be achieved in window
cropping mode as well, by fixing the mode registers
changes in v3:
- fix patch 2/6 where we need to free ctrl handler
on error path.
changes in v2:
- New patch 4/6
- Drop calculating the pixel clock from link freq.
- CCI register address sort (incremental)
- Fix cci_write for REG_HOLD handling and add a comment.
- Remove unused macros as part of 3/6
