* 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-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";
