Subject[PATCH v7 00/13] media: atmel: atmel-isc: implement media controller

This series is the v7 series that attempts to support media controller in the
atmel ISC and XISC drivers.
The CSI2DC driver was accepted thus removed from the patch series, together with
other patches.

Important note: this series applies on top of current media_staging tree, as it
relies on previous patches in the series which were accepted.

Thanks to everyone who reviewed my work !


Changes in v7:
-> scaler: modified crop bounds to have maximum isc size
-> format propagation: did small changes as per Jacopo review

Changes in v6:
-> worked a bit on scaler, added try crop and other changes as per Jacopo review
-> worked on isc-base enum_fmt , reworked as per Jacopo review

Changes in v5:
-> removed patch that removed the 'stop' variable as it was still required
-> added two new trivial patches
-> reworked some parts of the scaler and format propagation after discussions with Jacopo

Changes in v4:
-> as reviewed by Hans, added new patch to remove the 'stop' variable and reworked
one patch that was using it
-> as reviewed by Jacopo, reworked some parts of the media controller implementation

Changes in v3:
- change in bindings, small fixes in csi2dc driver and conversion to mc
for the isc-base.
- removed some MAINTAINERS patches and used patterns in MAINTAINERS

Changes in v2:
- integrated many changes suggested by Jacopo in the review of the v1 series.
- add a few new patches
