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-r8a7743" (RZ/G1M)
10 - "renesas,thermal-r8a7779" (R-Car H1)
11 - "renesas,thermal-r8a7790" (R-Car H2)
12 - "renesas,thermal-r8a7791" (R-Car M2-W)
13 - "renesas,thermal-r8a7792" (R-Car V2H)
14 - "renesas,thermal-r8a7793" (R-Car M2-N)
15- reg : Address range of the thermal registers.
16 The 1st reg will be recognized as common register
17 if it has "interrupts".
18
19Option properties:
20
21- interrupts : use interrupt
22
23Example (non interrupt support):
24
25thermal@ffc48000 {
26 compatible = "renesas,thermal-r8a7779", "renesas,rcar-thermal";
27 reg = <0xffc48000 0x38>;
28};
29
30Example (interrupt support):
31
32thermal@e61f0000 {
33 compatible = "renesas,thermal-r8a73a4", "renesas,rcar-thermal";
34 reg = <0xe61f0000 0x14
35 0xe61f0100 0x38
36 0xe61f0200 0x38
37 0xe61f0300 0x38>;
38 interrupts = <0 69 IRQ_TYPE_LEVEL_HIGH>;
39};
40
41Example (with thermal-zone):
42
43thermal-zones {
44 cpu_thermal: cpu-thermal {
45 polling-delay-passive = <1000>;
46 polling-delay = <5000>;
47
48 thermal-sensors = <&thermal>;
49
50 trips {
51 cpu-crit {
52 temperature = <115000>;
53 hysteresis = <0>;
54 type = "critical";
55 };
56 };
57 cooling-maps {

60};

63 compatible = "renesas,thermal-r8a7790",

65 "renesas,rcar-thermal";
66 reg = <0 0xe61f0000 0 0x14>, <0 0xe61f0100 0 0x38>;
67 interrupts = <0 69 IRQ_TYPE_LEVEL_HIGH>;
68 clocks = <&mstp5_clks R8A7790_CLK_THERMAL>;
