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?
