I prefer ordering these by the same order that we typically have in
device tree, so "compatible", "reg", "interrupts", "clocks",
"clock-names", "resets", "reset-names", "dmas", "dma-names". I find
that clearer because it lists the common properties at the top and
the less common ones (such as "dmas") at the bottom.

Anyway, it doesn't really matter, so:
