Thanks for pointing this out. It does seem like 'pvt@' is unusual:

$ git grep -l 'thermal-sensor@' arch/*/boot/dts | wc -l
57
$ git grep -l 'pvt@' arch/*/boot/dts | wc -l
1

$ git grep -l 'thermal-sensor@' Documentation/devicetree/bindings/ | wc -l
14
$ git grep -l 'pvt@' Documentation/devicetree/bindings/ | wc -l
2

The 6.17 PR for dts has already happened, so I'll do a fix once I can
update my thead-dt-fixes branch to 6.17-rc1.

thanks,
