I'm okay with taking this, but would like to have Matthias ack on the fact that we're breaking backwards compatibility with older DTS. (Or I could ack this and Matthias can take it together with the DT change, to reduce the breakage gap in the git history?)

Yes, it has associated DT changes. But the board "MT8192 SCP" is still under development, the DTS part hasn't been sent to upstream yet. Thus, it won't break anyone else.

Then I don't mind merging this, will include it in v5.11. Thank you, Bjorn

The correct MT8192 CFG register base is 0x20000 off. Changes the registers accordingly.
