Add thermal sensor support for r8a7743 SoC. The Renesas RZ/G1M (r8a7743) thermal sensor module is identical to the R-Car Gen2 family. No driver change is needed due to the fallback compatible value "renesas,rcar-gen2-thermal".

* 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.
|
|
Examples with soctypes are:
|
|
- "renesas,thermal-r8a73a4" (R-Mobile APE6)
|
|
- "renesas,thermal-r8a7743" (RZ/G1M)
|
|
- "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)
|
|
- reg : Address range of the thermal registers.
|
|
The 1st reg will be recognized as common register
|
|
if it has "interrupts".
|
|
|
|
Option properties:
|
|
|
|
- interrupts : use interrupt
|
|
|
|
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>;
