[v4,00/20] 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 01/20. 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 05/20 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. Compared to v3, patch 15/20 has been added, and the series has
been rebased on top of a merge of Sakari's sensors pull request for v6.7
and a v6.6 fixes branch that will appear in v6.6-rc3. This was necessary
as both of those branches contain imx219 changes that conflict with this
series. As a result of the rebase, patch 15/20 from v3 got dropped.

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