[PATCH 00/13] media/imx355: General code cleanups, and adding support for 2 lane operation

[Dave Stevenson <dave.stevenson@raspberrypi.com>]

This series came about as we had a customer ask about using imx355,
so I had a look at what was going on.

There was significant duplication between the various mode register lists,
unused parameters around, and no support for advertising the crop
rectangles through get_selection. It also wasn't using V4L2_CCI so
had all the boilerplate for writing registers.
The customer also wanted to run the sensor over only 2 CSI2 data lanes
which required some rework of the clock setup so that the MIPI link
frequency could be run at 445MHz instead of the 360MHz used for 4 lane
mode.

The first 11 patches are cleanups which should be fairly uncontroversial.
Patch 12 converts to use V4L2_CCI.
Finally patch 13 adds 2 lane support.

The series is based on sailus/next, with David Heidelberg's patch for
24MHz clock support added as that also suited my module.
(Linked in the dependencies).
