[PATCH 0/5] R-Car DU: Add support for R8A7793 and R8A7794

[Kuninori Morimoto]

Hi Laurent

> This patch series adds support for the DU found in the R8A7793 and R8A7794
> SoCs. It mostly consists of DT bindings updates (1/5 and 2/5) with a small
> driver change in 2/5 to support fixed RGB output routing. Patches 4/5 and 5/5
> then add DU nodes to the r8a7793.dtsi and r8a7794.dtsi, with patch 3/5 adding
> support for the DU0 clock to r8a7794.dtsi.
> 
> I will enable DU support for the Gose and Alt board in a later step when I'll
> have access to the schematics. I won't be able to test that due to lack of
> hardware though.
> 
> The R8A7794 datasheet documents as single DU clock named DU0, while the DU
> section documents DU0 and DU1 channels. I don't know at this point whether this
> is a datasheet mistake or if the DU0 clock drives both channels. I've opted for
> the latter, but I'd appreciate a confirmation.

I will check it. please wait
