Subject: Re: [PATCH V15 1/5] dt-bindings: fsl: scu: add thermal binding

Hi, Anson,

We're missing ACK from the maintainers for patch 4/5 and 5/5, if we
want to shipped the patch via thermal tree.

For patch 2/5, as it introduces a new API for OF_THERMAL, I'd like to
get Eduardo' feedback before taking them.

thanks,
rui
