The sort rule was not obvious as there are > many other nodes that don't conform. hmm, that is probably an oversight then :-) . Though looking through rk3588s.dtsi and rk3588.dtsi, it looks like most peripherals follow that sorting quite nicely. But there is also a bit of leeway ... aka there can be an argument made that assigned-clocks might want to live near clocks or regulator-properties could be sorted somewhat differently. So general ideal is alphabetically for the random properties to give some guidance on sorting. And compatible, regs, interrupts at the top + status at the bottom makes it way easier to establish a reading pattern, when looking for something in the file :-) .
