[PATCH v4 0/9] rcar-vin: Add support for parallel input on Gen3

[Jacopo Mondi <jacopo+renesas@jmondi.org>]

Hello,
   this series adds support for parallel video input to the Gen3 version of
rcar-vin driver.

Compared to v3, this new iteration closes all comments from Niklas and Sergei.

As the meat of the patch series hasn't changed much, please refer to v3 cover
letter for more details.

The most notable change is the great simplification of the parallel
input notifiers registration in [5/9], as now the media controller is
initialized before parallel inputs are parsed. As the media device is now
properly initialized, parallel input notifiers can be registered as soon as new
input devices are discovered, without having to wait for the group notifier
complete callback to be called. Thanks Niklas for pointing that out.

Testing:
Tested image capture on both Draak and Salvator-X M3-W with a fake parallel
input device added.

Test branch for Salvator-X available at
git://jmondi.org d3/media-master/salvator-x-dts_csi2/m3w-add_parallel_to_dts+driver-v4
For Draak at:
git://jmondi.org d3/media-master/salvator-x-dts_csi2/d3-vin-driver-v4+enable-HDMI-in-dts
(sorry for the horrid branch names :)

Niklas, I know you have a V3M with expansion that has both CSI-2 and parallel
input. Could you give this one a spin please?

No changelog reported here, except from the one reported above.

Most of the other changes are minors, the most notable ones are reported in
each patch commit message.

Thanks
   j
