Hi, Rob sir: Yes, my patch follows Documentation/devicetree/bindings/cpufreq/cpufreq-qcom-hw.txt way to define frequency domain. Is it OK to you if I use the same way to do? And if there exist any schema problem, please kindly let me know how to fix it. My patch reference Documentation/devicetree/bindings/thermal/thermal-cooling-devices.yaml to use the cpu node. https://elixir.bootlin.com/linux/v5.9-rc6/source/Documentation/devicetree/bindings/thermal/thermal-cooling-devices.yaml Thanks a lot.
