Please make sure that the parts you are sending upstream are actually
working on the upstream tree. Otherwise somebody might try running
upstream without extra patches and be surprised about it not working.

The patchseres in question was submitted in 2020 and got rejected. Since
that time we have added support for machine-specific firmware-N.bin, so
Kalle's suggestion can now be implemented easily.

Regarding the MDSS. Is it being solved by adding reset to the MDSS node?
Or are there any other issues?
