* Renesas R-Car Thermal
Required properties:
- compatible : "renesas,thermal-<soctype>",
"renesas,rcar-gen2-thermal" (with thermal-zone) or
"renesas,rcar-thermal" (without thermal-zone) as
fallback except R-Car V3M/E3/D3 and RZ/G2E.
Examples with soctypes are:
- "renesas,thermal-r8a73a4" (R-Mobile APE6)
- "renesas,thermal-r8a7743" (RZ/G1M)
- "renesas,thermal-r8a7744" (RZ/G1N)
- "renesas,thermal-r8a774c0" (RZ/G2E)
- "renesas,thermal-r8a7779" (R-Car H1)
- "renesas,thermal-r8a7790" (R-Car H2)
- "renesas,thermal-r8a7791" (R-Car M2-W)
- "renesas,thermal-r8a7792" (R-Car V2H)
- "renesas,thermal-r8a7793" (R-Car M2-N)
- "renesas,thermal-r8a77970" (R-Car V3M)
- "renesas,thermal-r8a77990" (R-Car E3)
- "renesas,thermal-r8a77995" (R-Car D3)
- reg : Address range of the thermal registers.
The 1st reg will be recognized as common register
if it has "interrupts".
Option properties:
- interrupts : If present should contain 3 interrupts for
R-Car V3M/E3/D3 and RZ/G2E or 1 interrupt otherwise.
Example (non interrupt support):
thermal@ffc48000 {
compatible = "renesas,thermal-r8a7779", "renesas,rcar-thermal";
reg = <0xffc48000 0x38>;
};
Example (interrupt support):
thermal@e61f0000 {
compatible = "renesas,thermal-r8a73a4", "renesas,rcar-thermal";
reg = <0xe61f0000 0x14
0xe61f0100 0x38
0xe61f0200 0x38
0xe61f0300 0x38>;
interrupts = <0 69 IRQ_TYPE_LEVEL_HIGH>;
};
Example (with thermal-zone):
thermal-zones {
cpu_thermal: cpu-thermal {
polling-delay-passive = <1000>;
polling-delay = <5000>;
thermal-sensors = <&thermal>;
trips {
cpu-crit {
temperature = <115000>;
hysteresis = <0>;
type = "critical";
};
};
cooling-maps {
};
};
};
thermal: thermal@e61f0000 {
compatible = "renesas,thermal-r8a7790",
"renesas,rcar-gen2-thermal",
"renesas,rcar-thermal";
reg = <0 0xe61f0000 0 0x14>, <0 0xe61f0100 0 0x38>;
interrupts = <0 69 IRQ_TYPE_LEVEL_HIGH>;
clocks = <&mstp5_clks R8A7790_CLK_THERMAL>;
power-domains = <&cpg_clocks>;
#thermal-sensor-cells = <0>;
};
