Thanks for submitting this. A quick scan indicates it should work with a

Shouldn't those properties be sorted alphabetically? Or at least consistently?
Note that the same issue is present on other places too, but I believe the
above quoted part shows the issue enough.
The main sorting is
- compatible
- reg
[... alphabetically ...]
- status
Yeah ... that's always the question when adding new board files. Do it like
"it's always been done" or re-sort the properties alphanumeric _everywhere_
which looks quite strange at times. If I'm getting the newly added dt
coding style correctly common (subsystem?) properties should also be placed
before vendor (driver?) specific ones. Yet I didn't see a board file which
places 'regulator-max-microvolt' before 'regulator-min-microvolt'. So I
guess it's fine if it's done consistently within the same file?

But now that I look at it, you're right there are some non-alphabetical
shenanigans going on there in the sdmmc and sdhci nodes ;-)
