Hi Dan,
Sascha's thermal driver V12 only register sensor id as 0, so we need to
register sensor id as 0 to device tree as well.

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.

BR,
Dawei
