Add support for R-Car Gen3/Gen4 and RZ/G2 thermal sensors.
Fuse readout support is present, including fallback trimming.
Example usage using the 'temperature' command on R-Car V4H Sparrow Hawk:
"
=> temperature list
| Device | Driver | Parent
| thermal-rcar-gen3-tsc.0 | thermal-rcar-gen3-tsc | thermal@e6198000
| thermal-rcar-gen3-tsc.1 | thermal-rcar-gen3-tsc | thermal@e6198000
| thermal-rcar-gen3-tsc.2 | thermal-rcar-gen3-tsc | thermal@e6198000
| thermal-rcar-gen3-tsc.3 | thermal-rcar-gen3-tsc | thermal@e6198000
=> for i in 0 1 2 3 ; do temperature get thermal-rcar-gen3-tsc.$i ; done
thermal-rcar-gen3-tsc.0: 56 C
thermal-rcar-gen3-tsc.1: 50 C
thermal-rcar-gen3-tsc.2: 48 C
thermal-rcar-gen3-tsc.3: 52 C

Enable support for temperature-sensing devices. Some SoCs have on-chip
|
|
temperature sensors to permit warnings, speed throttling or even
|
|
automatic power-off when the temperature gets too high or low. Other
|

devices may be discrete but connected on a suitable bus.
