[PATCH v5 00/13] media: atmel: atmel-isc: implement media controller

[Eugen Hristev]

This series is the v5 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 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
