Sorry for late reply. This patch was verified with HDMI display on M3W and H3 ULCB boards with following patches applied: https://patchwork.kernel.org/patch/9688551/ https://patchwork.kernel.org/patch/9831835/ https://patchwork.kernel.org/patch/9801239/

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.
