[PATCH 0/4] rcar-du: add R8A774[35] DU driver(s) support

[PATCH 0/4] rcar-du: add R8A774[35] DU driver(s) support

[Fabrizio Castro]

In order to be able to define du nodes in r8a7743 and r8a7745 device
trees, we need to define data structures, compatible strings, missing
clock, and update the dt-bindings.
I'll send out the patches to add the du nodes in r8a774[35] device trees
once the patches in this series get accepted.

Best regards,

[PATCH 1/4] dt-bindings: display: rcar-du: Document R8A774[35] DU

[Fabrizio Castro]

Add device tree bindings for r8a7743 and r8a7745 DUs.
r8a7743 DU is similar to the one from r8a7791, r8a7745 DU is similar
to the one from r8a7794.

How about "All other DU instances use one functional clock..." ? I expect more 
entries to the added in the future, it would be nice not to have to modify 
this paragraph.

When there's a single DPAD the table mentions "DPAD" instead of "DPAD 0". 
There's no specific reason for that other than a historical one, but to keep 
entries consistent I would either keep doing so, or rename DPAD to DPAD 0 in 
all existing entries. What would you prefer ?

If you're fine with these changes there's no need to submit a new version, I 
can fix when applying the patch to my tree.

My personal preference is to number all of the entries (not just DPAD ones).

[PATCH 2/4] drm: rcar-du: Add R8A7743 support

[Fabrizio Castro]

Add support for the R8A7743 DU (which is very similar to the R8A7791 DU);
it has 1 DPAD (RGB) output and 1 LVDS output.
