Sorry about the delay here. I noticed this as I was doing a final pass
on the review comments before reposing.
I'm guessing you didn't see it because because I messed up the patch

It should all be merged(ing), there was a patch in 5.11 to handle the
sdhci-caps[-mask] fields, and the ACPI ID's patch should be getting
merged to 5.12. The linux-firmware patch was merged a month or so ago
too, which enables wifi. This is the last piece of the puzzle.
