My short list.
There is no hard rule... It mostly depend on Heiko...
For nodes:
If exists on top: model, compatible and chosen.
Sort things without reg alphabetical first,
then sort the rest by reg address.
Inside nodes:
If exists on top: compatible, reg and interrupts.
In alphabetical order the required properties.
Then in alphabetical order the other properties.
And as last things that start with '#' in alphabetical order.
Add status below all other properties for soc internal components with
any board-specifics.
Keep an empty line between properties and nodes.
Exceptions:
Sort pinctrl-0 above pinctrl-names, so it stays in line with clock-names
and dma-names.
Sort simple-audio-card,name above other simple-audio-card properties.
Sort regulator-name above other regulator properties.
Sort regulator-min-microvolt above regulator-max-microvolt.
