These are the two fixes I successfully tested to mitigate #7301

Any fixes to code that is unchanged in our downstream (rpi-7.0.y) kernel will need to be submitted upstream.
See here.

Thanks, and I'm trying to get this done, but it is not trivial for a non-kernel developer, as it appears; have reached out via email to check.

The two regarding RP1 (6b29188 and 0504cd9) are independent of the others, only for Pis with the RP1 and not related to upstream linux, if I'm not mistaken? I should have created two pull requests, my mistake, I'm sorry.

Yes, I think the RP1 commits affect downstream code, so belong here.

The PPS commits looked to be editing files we haven't changed downstream, so belong upstream.
We can pick them up once they are accepted upstream, but the (upstream) code devs are in a better position to judge the changes to be correct (and advise if not).
