> V2 -> V4: moved back to thermal (not using bcm sub-directory)

> V5 -> V6: added correct depends in KConfig
> removed defined default for RESET_DELAY
> removed obvious comments
> clarify HW setup comments if not set up by FW already
> move clk_prepare_enable to an earlier stage and add error handling
> clarify warning when TS-clock runs out of recommended range
> clk_disable_unprepare added in bcm2835_thermal_remove
> added comment on recommended temperature ranges for SOC
> V6 -> V7: removed depends on ARCH_BCM2836 || ARCH_BCM2837 in Kconfig
> V7 -> V8: rebased
> V8 -> V9: moved to use the thermal framework offset and slope in

> V10 -> V11: fix parse issue in bcm2837.dtsi, fix probing and remove unused tzp
