I guess the order shall be: 1. compatible 2. reg 3. #address-cells (if applicable) #size-cells (if applicable) 4. ranges (if applicable) 5. Standard/common properties ordered alphabetically (ex. clocks, interrupts, pinctrl) 6. vendor-specific properties 7. status (if applicable) Please let me know if you have other preference. Thanks! ta
