1 | * Renesas R-Car Thermal |
| 2 | ||
| 3 | Required properties: | |
| 8b477ea5 KM |
4 | - compatible : "renesas,thermal-<soctype>", |
| 5 | "renesas,rcar-gen2-thermal" (with thermal-zone) or | |
| 6 | "renesas,rcar-thermal" (without thermal-zone) as fallback. | |
| fa313103 | 7 | Examples with soctypes are: |
| 2771d000 | 8 | - "renesas,thermal-r8a73a4" (R-Mobile APE6) |
| fa313103 GU |
9 | - "renesas,thermal-r8a7779" (R-Car H1) |
| 10 | - "renesas,thermal-r8a7790" (R-Car H2) | |
| 689bd24c GU |
11 | - "renesas,thermal-r8a7791" (R-Car M2-W) |
| 12 | - "renesas,thermal-r8a7792" (R-Car V2H) | |
| 13 | - "renesas,thermal-r8a7793" (R-Car M2-N) | |
| 14 | - "renesas,thermal-r8a7794" (R-Car E2) | |

15 | - reg : Address range of the thermal registers. |
| 16 | The 1st reg will be recognized as common register | |
| 17 | if it has "interrupts". | |
| 18 | ||
| 19 | Option properties: | |
| 20 | ||
| 21 | - interrupts : use interrupt | |
| 22 | ||
| 23 | Example (non interrupt support): | |
