Thanks for the list.  I was able to successfully build the stable 6.6
branch with those patches applied and I have the HDMI working.
Unfortunately, I get build errors on the linux-next, so it's going to
take me a little time to sort through all of this.

I am thinking that it would be better to consolidate all these
together into one series instead of piecemealing it.  However, there
are some items that can be submitted right away without significantly
reworking them against linux-next.  Do people have a preference?
