Hi Rob,

I think Balsam took into account your comments. Is it fine for you ?

Subject: drop second/last, redundant "dt-binding definition". The
"dt-bindings" prefix is already stating that these are bindings.

Plus two comments at the end.

Same filename as bindings.

Although this is correct, any reason why not using exactly the same
license as bindings?

The patchset was not sent to us at all, so it is the second version we
see. Therefore it's not v12 for us. It's v2 and it still needs fixes.

I replied with minor comments (which could be fixed during applying) and
the license concern (which you rather cannot change while applying).

Best regards,
Krzysztof

fixed.
The patch title has been fixed as you suggested :
"dt-bindings: thermal: mediatek: Add LVTS thermal controllers"

I apologize for forgetting to add some email addresses while sending
previous versions.
The changes you asked in your preview comment are taken in account and
ready to be sent.
Please let me know what version number should the patch have.

I think it should be
include/dt-bindings/thermal/mediatek,lvts-thermal.yaml

OK,
I will change it like that.
(".h" and not ".yaml" I believe (just to be sure).).

Missing coma, so mediatek,lvts-thermal.h

Yeah, actually Balsam resent a new version but numbered v3 taking into

The versioning is becoming a bit messy now but if you are ok with the 
changes I'll pick the patch as is so we can go forward for this series.
