[PATCH 0/2] thermal/drivers/rcar_gen3: Add support for R-Car V4M

[Geert Uytterhoeven]

	Hi all,

This patch series adds support for the Thermal Sensor/Chip Internal
Voltage Monitor/Core Voltage Monitor (THS/CIVM/CVM) on the Renesas R-Car
V4M (R8A779H0) SoC.

It has been tested on the Renesas Gray Hawk Single development board,
with an R-Car V4M SoC that has unfortunately no calibration values
fused.

Thanks for your comments!

[PATCH 1/2] dt-bindings: thermal: rcar-gen3-thermal: Add r8a779h0 support

[Geert Uytterhoeven]

From: Duy Nguyen <duy.nguyen.rh@renesas.com>

Document support for the Thermal Sensor/Chip Internal Voltage
Monitor/Core Voltage Monitor (THS/CIVM/CVM) on the Renesas R-Car V4M
(R8A779H0) SoC.

Just like on other R-Car Gen4 SoCs, interrupts are not routed to the
INTC-AP (GIC) but to the Error Control Module (ECM).

Changes compared to the BSP:
  - No interrupts property, as interrupts are routed to the ECM.

[PATCH 2/2] thermal/drivers/rcar_gen3: Add support for R-Car V4M

[Geert Uytterhoeven]

Add support for the Thermal Sensor/Chip Internal Voltage Monitor/Core
Voltage Monitor (THS/CIVM/CVM) on the Renesas R-Car V4M (R8A779H0) SoC.

The conversion formulas for R-Car V4M are the same as for other R-Car
Gen4 SoCs.

Based on a patch in the BSP by Duy Nguyen.
