[PATCH 1/2] dt-bindings: thermal: rcar: Add device tree support for r8a7743

[Biju Das]

Add thermal sensor support for r8a7743 SoC. The Renesas RZ/G1M
(r8a7743) thermal sensor module is identical to the R-Car Gen2 family.

No driver change is needed due to the fallback compatible value
"renesas,rcar-gen2-thermal".

[PATCH 2/2] ARM: dts: r8a7743: Add thermal device to DT

[Biju Das]

This patch instantiates the thermal sensor module with thermal-zone
support.

This patch is based on the commit cac68a56e34b
("ARM: dts: r8a7791: enable to use thermal-zone") by Kuninori Morimoto.

The register at offset 0x10 seems to exist on R-Mobile APE6 only, but
all R-Car Gen2 .dtsis include it in the range...

Not that it matters much, mapping granularity is PAGE_SIZE anyway...
