1 | * Renesas R-Car PWM Timer Controller |
| 2 | ||
| 3 | Required Properties: | |
| 4 | - compatible: should be one of the following. | |
| 5 | - "renesas,pwm-rcar": for generic R-Car compatible PWM Timer | |
| 6 | - "renesas,pwm-r8a7778": for R-Car M1A | |
| 7 | - "renesas,pwm-r8a7779": for R-Car H1 | |
| 8 | - "renesas,pwm-r8a7790": for R-Car H2 | |
| 9 | - "renesas,pwm-r8a7791": for R-Car M2-W | |
| 10 | - "renesas,pwm-r8a7794": for R-Car E2 | |
| 11 | - reg: base address and length of the registers block for the PWM. | |
| 12 | - #pwm-cells: should be 2. See pwm.txt in this directory for a description of | |
| 13 | the cells format. | |
| 14 | - clocks: clock phandle and specifier pair. | |
| 15 | - pinctrl-0: phandle, referring to a default pin configuration node. | |
| 16 | - pinctrl-names: Set to "default". | |
| 17 | ||
| 18 | Example: R8A7790 (R-Car H2) PWM Timer node | |
| 19 | ||
| 20 | pwm0: pwm@e6e30000 { | |
| 21 | compatible = "renesas,pwm-r8a7790", "renesas,pwm-rcar"; | |
| 22 | reg = <0 0xe6e30000 0 0x8>; | |
| 23 | #pwm-cells = <2>; | |
| 24 | clocks = <&mstp5_clks R8A7790_CLK_PWM>; | |
| 25 | pinctrl-0 = <&pwm0_pins>; | |
| 26 | pinctrl-names = "default"; | |
| 27 | }; |
