| * 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"; |
| 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>; |
| }; |
