[PATCH 00/21] media: atmel: atmel-isc: implement media controller

[Eugen Hristev]

This series is a first attempt to support media controller in the atmel
ISC and XISC drivers.
This series also includes the csi2dc driver which was previously sent in a
separate series:
https://www.spinics.net/lists/linux-media/msg181042.html
https://www.spinics.net/lists/linux-media/msg181044.html
The driver now addresses comments received in latest v5 series from last year.

The series includes some minor changes and fixes that improve the isc common
code base, like removing the enum frameintervals VIDIOC, fixing bytesperline
for planar formats, etc.

Many thanks to folks from libcamera who helped a lot with understanding
how a media controller driver should behave.

Feedback is welcome !
