There's a naming convention for the BCM DT bindings these days where you
basically name it after the compatible string, so this file should be
moved to "brcm,bcm2835-thermal.txt" (yes, even though it's inconsistent
with the rest of the files in the directory).

Optional: change to 'should be: "brcm,bcm2835-thermal" or
"brcm,bcm2837-thermal"' (see next review for explanation).

I would also drop the space before the colons on the parameters, but as
long as the filename is changed this patch is:
