Hi, this patchset introduces cropping support for the Sony IMX274 sensor using the SELECTION API, after several cleanups and general code improvements. Patches 1-6 clean up and restructure code in various places and are pretty much independent from the cropping feature. Patches 7-11 are further restructuring which are mostly useful to implement cropping API in a cleaner way. Patch 12 introduces a helper to allow setting many registers computed at runtime in a straightforward way. This would not have been very useful before because all long register write sequences came from const tables, but it's definitely a must for the cropping code. Patch 13 implements cropping in the set_selection pad operation. On the v4l2 side there is nothing special, it fit nicely in the existing infrastructure. The most tricky part was respecting all the device constraints on the horizontal crop.
