Merge branch 'fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/evalenti/linux-soc-thermal
Pull thermal management fixes from Eduardo Valentin: "Specifics in this pull request: - Compilation fixes on SPEAR, and U8500 thermal drivers. - RCAR thermal driver now recognizes OF-thermal based thermal zones. - Small code rework on OF-thermal. - These change have been CI tested using KernelCI bot [1,2]. \o/ I am taking over on Rui's behalf while he is out. Happy New Chinese Year!

* Renesas R-Car Thermal
Required properties:
-- compatible : "renesas,thermal-<soctype>", "renesas,rcar-thermal"
- as fallback.
+- compatible : "renesas,thermal-<soctype>",
+ "renesas,rcar-gen2-thermal" (with thermal-zone) or
+ "renesas,rcar-thermal" (without thermal-zone) as fallback.
Examples with soctypes are:
- "renesas,thermal-r8a73a4" (R-Mobile APE6)
- "renesas,thermal-r8a7779" (R-Car H1)
