Subject: [PATCH v4 00/11] media: atmel: atmel-isc: implement media controller
This series is the v4 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.
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
Thanks to everyone who reviewed my work !
Eugen
Previous cover letter from v3:
This series is the v3 of the series that attempts 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 !
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
