Hi Laurent, again
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
According to HW team, MSTP page of datasheet seems wrong Maybe you have already tried, but, can you access to MSTPSR1 :: 27bit (for DU1)
I would try if I had access to an Alt board :-)
Magnus, do you have an Alt board I could access remotely ?
Not sure if it is hooked up right now, but I will make sure you can get access sometime soon.
Cheers,
