Hi,
i've found it :)
hdmi-problem is caused by
commit 440147639ac79f699a4eb9811d0bc39d3cc815f4
Author: CK Hu <ck.hu@xxxxxxxxxxxx>
Date: Wed Mar 17 19:17:10 2021 +0100
soc: mediatek: mmsys: Use an array for setting the routing registers
but i cannot revert it alone, but after reverting all mmsys-patches hdmi works (ovl irq-handler called)
$ git logone v5.12..v5.13-rc1 -- drivers/ | grep 'mtk\|mediatek' | grep mmsys
060f7875bd23 2021-04-05 soc: mediatek: mmsys: Add support for MT8167 SoC
1ff1270fca33 2021-03-30 soc: mediatek: mmsys: Add mt8183 mmsys routing table
440147639ac7 2021-03-17 soc: mediatek: mmsys: Use an array for setting the routing registers
ce15e7faa2fc 2021-03-17 soc: mediatek: mmsys: Create struct mtk_mmsys to store context data
git revert 060f7875bd23 1ff1270fca33 440147639ac7 ce15e7faa2fc
and after reapplying them one-by-one it stops working on commit above (440147639ac7)
@Dafna can you confirm it solves your issue too?
btw. watchdog issue is caused by
commit bbece05c0d3a96817483e0b249ad1e302ba95117
watchdog: mtk_wdt: Remove mtk_wdt_stop() in probe() to prevent the system freeze and it doesn't reboot by watchdog problem
have already contacted author
regards Frank
