* Changes since v2
- Use reg = <0xe6198000 0x100> instead of reg = <0 0xe6198000 0 0x100>
in examples due to #{address,size}-cells = <1>.
* Changes since v1
- Improved on reg and interrupt descriptions with the use of 'items:'
- Improved the examples inside the yaml file
- Added compatibility value renesas,r8a77961-thermal for R-Car M3-W+
which was merged in the text binding description.

-* DT bindings for Renesas R-Car Gen3 Thermal Sensor driver
-
-On R-Car Gen3 SoCs, the thermal sensor controllers (TSC) control the thermal
-sensors (THS) which are the analog circuits for measuring temperature (Tj)
-inside the LSI.
-
-Required properties:
-- compatible : "renesas,<soctype>-thermal",
- Examples with soctypes are:
- - "renesas,r8a774a1-thermal" (RZ/G2M)
- - "renesas,r8a774b1-thermal" (RZ/G2N)
- - "renesas,r8a7795-thermal" (R-Car H3)
- - "renesas,r8a7796-thermal" (R-Car M3-W)
- - "renesas,r8a77961-thermal" (R-Car M3-W+)
- - "renesas,r8a77965-thermal" (R-Car M3-N)
- - "renesas,r8a77980-thermal" (R-Car V3H)
-- reg : Address ranges of the thermal registers. Each sensor
- needs one address range. Sorting must be done in
- increasing order according to datasheet, i.e.
- TSC1, TSC2, ...
-- clocks : Must contain a reference to the functional clock.
-- #thermal-sensor-cells : must be <1>.
-
-Optional properties:
-
-- interrupts : interrupts routed to the TSC (must be 3).
-- power-domain : Must contain a reference to the power domain. This
- property is mandatory if the thermal sensor instance
- is part of a controllable power domain.
-
-Example:
-
- tsc: thermal@e6198000 {
- compatible = "renesas,r8a7795-thermal";
- reg = <0 0xe6198000 0 0x100>,
- <0 0xe61a0000 0 0x100>,
- <0 0xe61a8000 0 0x100>;
- interrupts = <GIC_SPI 67 IRQ_TYPE_LEVEL_HIGH>,
- <GIC_SPI 68 IRQ_TYPE_LEVEL_HIGH>,
- <GIC_SPI 69 IRQ_TYPE_LEVEL_HIGH>;
- clocks = <&cpg CPG_MOD 522>;
- power-domains = <&sysc R8A7795_PD_ALWAYS_ON>;
- #thermal-sensor-cells = <1>;
- };
-
- thermal-zones {
- sensor_thermal1: sensor-thermal1 {
- polling-delay-passive = <250>;
- polling-delay = <1000>;
- thermal-sensors = <&tsc 0>;
-
- trips {
- sensor1_crit: sensor1-crit {
