No, I mean for all cases of <nodename>-N, can be we consistent. Either we use hex or we use decimal. > > These can be found with: > > $ find Documentation/devicetree/bindings/ -name \*.yaml | \ > xargs grep pattern: | grep '\[0-9a-f\]' | grep -v '\[0-9a-f\]+' Not quite. It's just cases of '-N': $ find Documentation/devicetree/bindings/ -name \*.yaml | xargs grep pattern: | grep '\-\[0-9a-f\]' | grep -v '\[0-9a-f\]+' Documentation/devicetree/bindings/phy/intel,combo-phy.yaml: pattern: "combophy(@.*|-[0-9a-f])*$" Documentation/devicetree/bindings/pwm/pwm.yaml: pattern: "^pwm(@.*|-[0-9a-f])*$" Documentation/devicetree/bindings/timestamp/hardware-timestamps-common.yaml: pattern: "^timestamp(@.*|-[0-9a-f])?$" Documentation/devicetree/bindings/watchdog/watchdog.yaml: pattern: "^watchdog(@.*|-[0-9a-f])?$" Documentation/devicetree/bindings/spi/spi-controller.yaml: pattern: "^spi(@.*|-[0-9a-f])*$" Documentation/devicetree/bindings/rtc/rtc.yaml: pattern: "^rtc(@.*|-[0-9a-f])*$" And there's probably some more in dtschema. > > Not sure if some of these need to intentionally limit the node numbering > to 15. No, I think it was all just cases of 15 should be enough for anyone. > > If you have some other criteria in mind, let me know :) If the numbering is hex, then it is as you have it. (Though we can't enforce that. If it is decimal, then the regex should be ([0-9]|[1-9][0-9]+). Rob
