Subject: [PATCH 00/19] Omnivision OV4689 refactoring and improvements

Hi,

This series contains refactoring and new features implementation for
the Omnivision OV4689 sensor driver. Specifically, patches 1, 2, 4, 5,
6, 9, 14, 15, 17, and 18 are refactorings, and are not supposed to
introduce any functional change. Patches 3 and 7 perform migration to
CCI helpers and subdevice active state respectively, and should not
introduce any hardware- and/or user-visible change either.

Patches 10-13 expose more sensor controls to the userspace, such as
(read-write) HBLANK, VFLIP/HFLIP, digital gain, and color
balance. Patch 16 implements configurable analogue crop rectangle via
.set_selection callback. And finally, patch 19 enables 2x2 binning
option. It should be noted that publicly available sensor
documentation is lacking description of many registers and their value
ranges, so a lot of values had to be found by experimentation.

Any comments and reviews are welcome!
