1* DT bindings for Renesas R-Car Gen3 Thermal Sensor driver
2
3On R-Car Gen3 SoCs, the thermal sensor controllers (TSC) control the thermal
4sensors (THS) which are the analog circuits for measuring temperature (Tj)
5inside the LSI.
6
7Required properties:
8- compatible		: "renesas,<soctype>-thermal",
9			  Examples with soctypes are:
10			    - "renesas,r8a7795-thermal" (R-Car H3)
11			    - "renesas,r8a7796-thermal" (R-Car M3-W)
12			    - "renesas,r8a77965-thermal" (R-Car M3-N)
13- reg			: Address ranges of the thermal registers. Each sensor
14			  needs one address range. Sorting must be done in
15			  increasing order according to datasheet, i.e.
16			  TSC1, TSC2, ...
17- clocks		: Must contain a reference to the functional clock.
18- #thermal-sensor-cells : must be <1>.
19
20Optional properties:
21
22- interrupts           : interrupts routed to the TSC (3 for H3, M3-W and M3-N)
23- power-domain		: Must contain a reference to the power domain. This
24			  property is mandatory if the thermal sensor instance
25			  is part of a controllable power domain.
