There is no hard rule... It mostly depend on Heiko...
For nodes:
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.
