[v2,00/18] media: i2c: imx219: Miscellaneous cleanups and improvements

Hello,

This patch series is a collection of miscellaneous cleanups and
improvements to the imx219 driver.

Most notably, the series starts with converting the driver to the new
CCI helpers ([1]) in 01/18. Unlike the IMX290, IMX296, IMX297 and IMX327
that have little-endian register values, this sensor adheres to the CCI
specification, so the conversion was possible. It caused a regression
that I had a bit of trouble tracking though, which showed that merging
conversion to the CCI helpers without testing would be dangerous.

Patch 04/18 fixes what I believe is an issue with the test pattern
generator configuration in 640x480 mode, and should be the only
functional change in the series.

For details about other patches, please see their individual commit
logs.

The series is based on the latest media master branch, with two
additional fixes for the imx219 driver (posted in [2]) that should make
it to v6.6, while the 18 patches here are v6.7 material.

The changes have been tested on a Raspberry Pi 4, with all the modes
supproted by the driver.
