Subject: [PATCH v2 00/13] media: i2c: imx214: Miscellaneous cleanups and
 improvements

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.

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
- Add A-b tags
