Either <&thermal 0> or <&thermal>, sensor id should be 0 for two cases. I try this two case, function all work fine for two cases. May I have any misunderstand? Please kindly give your comment. I will re-send this patch again once you tell me the reason, thank you.

In the new patchset, Sascha changed it to: #thermal-sensor-cells = <0>; Which means the <&thermal> phandle no longer has any arguments.

Yes, I don't need to add sensor id since new driver add thermal-sensor-cell as 0. (Even I checked function OK to this patch with new patchset) I will re-send this patch soon, thank you.
