[PATCH v2 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 v2 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.

RE: [PATCH v2 2/2] ARM: dts: r8a7743: Add thermal device to DT

Hi Simon,

Just noticed that

# make dtbs W=1 is giving below warning message.

arch/arm/boot/dts/r8a7743-iwg20d-q7-dbcm-ca.dtb: Warning (simple_bus_reg): Node /soc/thermal-zones missing or empty reg/ranges property

Do you prefer a fix patch or a v2 ?

Regards,
Biju

Hi Simon,

Just noticed that

# make dtbs W=1 is giving below warning message.

arch/arm/boot/dts/r8a7743-iwg20d-q7-dbcm-ca.dtb: Warning (simple_bus_reg): Node /soc/thermal-zones missing or empty reg/ranges property

Do you prefer a fix patch or a v2 ?

Biju

I believe I have fixed that by applying
"ARM: dts: r8a7743: move timer and thermal-zones nodes out of bus"

Could you check the devel branch when I push it a little later today?

Thanks, I will check and provide feedback if any.
