1* Renesas R-Car Thermal
2
3Required properties:
4- compatible : "renesas,thermal-<soctype>",
5 "renesas,rcar-gen2-thermal" (with thermal-zone) or
6 "renesas,rcar-thermal" (without thermal-zone) as fallback.
7 Examples with soctypes are:
8 - "renesas,thermal-r8a73a4" (R-Mobile APE6)
9 - "renesas,thermal-r8a7779" (R-Car H1)
10 - "renesas,thermal-r8a7790" (R-Car H2)
11 - "renesas,thermal-r8a7791" (R-Car M2-W)
12 - "renesas,thermal-r8a7792" (R-Car V2H)
13 - "renesas,thermal-r8a7793" (R-Car M2-N)
14- reg : Address range of the thermal registers.
15 The 1st reg will be recognized as common register
16 if it has "interrupts".
17
18Option properties:
19
20- interrupts : use interrupt
21
22Example (non interrupt support):
23
24thermal@ffc48000 {
25 compatible = "renesas,thermal-r8a7779", "renesas,rcar-thermal";
26 reg = <0xffc48000 0x38>;
27};
28
29Example (interrupt support):
30
31thermal@e61f0000 {
32 compatible = "renesas,thermal-r8a73a4", "renesas,rcar-thermal";
33 reg = <0xe61f0000 0x14
34 0xe61f0100 0x38
35 0xe61f0200 0x38
36 0xe61f0300 0x38>;
37 interrupts = <0 69 IRQ_TYPE_LEVEL_HIGH>;
38};
39
40Example (with thermal-zone):
41
42thermal-zones {
43 cpu_thermal: cpu-thermal {
44 polling-delay-passive = <1000>;
45 polling-delay = <5000>;
46
