The DU is already wired up to the HDMI encoder, all we need to do is enable it.

As no display is connected to the HDMI output testing was limited, to probing the device and verifying that it can be accessed from userspace. Tests on the H3 ES1.1 and H3 ES2.0 ULCBs were less successful as I couldn't get the boards to boot properly, but they failed without this patch as well, so I don't think it should be a blocker. diff --git a/arch/arm64/boot/dts/renesas/ulcb.dtsi b/arch/arm64/boot/dts/renesas/ulcb.dtsi index 1b868df2393f..dfec9072718b 100644 --- a/arch/arm64/boot/dts/renesas/ulcb.dtsi +++ b/arch/arm64/boot/dts/renesas/ulcb.dtsi @@ -157,6 +157,10 @@ }; }; +&du { + status = "okay"; +}; + &ehci1 { status = "okay"; }; -- Regards, Laurent Pinchart
