[PATCH v3 00/12] media: i2c: imx214: Miscellaneous cleanups and improvements

[André Apitzsch via B4 Relay]

This patch series is a collection of miscellaneous cleanups and
improvements to the imx214 driver.

The series converts the driver to the CCI helpers and adds controls
needed to make the driver work with libcamera.

The changes are inspired by the imx219 driver.

- Also keep previous link freq for backward compatibility
- Move link freq patch to the end of the series
- Remove return-early check from imx214_set_format()
- Remove unneeded struct imx214 function parameter
- Use correct ret value on number of data lanes error
- Revert changing order (imx214_parse_fwnode, devm_kzalloc)
- Fix typo
- Remove unused definition IMX214_EXPOSURE_MAX
- Don't set FPS to default
- Simplify exposure_def definition
- Set state and format only if control id is V4L2_CID_VBLANK
- Restore Ricardo's message to Sony
- Drop "media: i2c: imx214: Extract format and crop settings" patch
- Add A-b tag
- Link to v2: https://lore.kernel.org/r/20241021-imx214-v2-0-fbd23e99541e@xxxxxxxxxxx

Changes in v2:
- Add patch to fix link frequency
- Don't use and remove fmt and crop from struct imx214
- Squash patch 1/13 and 2/13
- Only check if #lanes == 4
- Add comment that enum_frame_interval() shouldn't be used by userspace
- Set V4L2_CID_VBLANK step size to 2 (according to datasheet Table 4-4)
- Increase IMX214_VBLANK_MIN to limit max frame rate of full resolution
  to the documented 30 fps
- As bpp is always 10, simplify setting IMX214_REG_CSI_DATA_FORMAT and
  IMX214_REG_OPPXCK_DIV
- Simplify imx214_get_format_code()
- Cluster hflip and vflip
- Remove kernel log note from 11/13, issue was fixed by a kernel update
