Subject: [PATCH v2 00/13] media: imx274: cleanups, improvements and SELECTION API support

Hi,

this patchset introduces cropping support for the Sony IMX274 sensor
using the SELECTION API.

With respect to v1 this patchset adds the "media: " prefix to commits
and fixes a warning in patch 9.

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. The most tricky part was
respecting all the device constraints on the horizontal crop.

Regards,
Luca
