[PATCH 0/2] Renesas R-Car Gen3 DU alpha and z-order support

[PATCH 0/2] Renesas R-Car Gen3 DU alpha and z-order support

[Laurent Pinchart]

Hello,

This patch series implement support for alpha and z-order configuration in the
R-Car DU driver for the Gen3 SoCs family.

The Gen3 SoCs delegate composition to an external IP core called VSP,
supported by a V4L2 driver. The DU driver interfaces with the VSP driver using
direct function calls. Alpha and z-order configuration is implemented in the
VSP driver, the DU driver thus just needs to pass the values using the VSP
API.

This series depends on a large VSP series that has been merged in the Linux
media git tree for v4.7. Dave, instead of merging the media tree in your tree
to pull the dependency in, it would be easier to get those two patches
upstream through the media tree. I don't expect any conflict related to the
DU driver for v4.7. If you're fine with that, could you ack the patches ?

There's lots of effort by various people to create a generic zpos/blending
set of properties. Care to jump onto that effort and making it finally
happen for real? I kinda don't want to have a propliferation of slightly
diffferent zpos/blending props across all the drivers ...

OK, I'll try to. Would you mind if we got these patches merged first for v4.7, 
and then switched to a generic property for v4.8 ? The reason is that this 
series depends on a large patch series queued in the linux-media tree for 
v4.7, and it would be easier to handle the dependency by merging these two 
patches in linux-media. A rework of the zpos and alpha properties would need 
to be merged through the drm tree.

I'd just love to see some real push to generic props for this entire area
happen for real. If you volunteer I'm more than happy enough already, 4.8
is perfectly fine.

Might be good to dig through older versions of this, we have iirc
conversions for most drivers. Also I highly recommend to do one series per
property, to avoid stalls due to bikesheds. And maybe start with zpos,
that one seems simplest ;-)

Thanks a lot for volunteering!

Cheers, Daniel
