If patches are well written and can be standalone, we (maintainers)
ideally prefer to queue things on a per subsystem basis, because it's
just easier.

That said, I also noticed that a new compatible string was added,
"intel,thunderbay-sdhci-5.1". This needs to be documented in
Documentation/devicetree/bindings/mmc/arasan,sdhci.yaml, in a separate
patch, preceding $subject patch.

Kind regards
