Hi Simon,

This patch depends on '[PATCH 0/2] thermal: rcar_gen3_thermal: add 
r8a77965 support'. So it's probably best you hold back applying it to 
such time it's dependency are accepted. I post it in any case to get 
review comments and keep it ready for future integration in 
renesas-drivers branches.

It also uses numerical values for the power-doamains propery as the 
defines where not yet available for me. This shall of course be updated 
before they are accepted.
