* Renesas R-Car PWM Timer Controller
|
|
|
|
Required Properties:
|
|
- compatible: should be "renesas,pwm-rcar" and one of the following.
|
|
- "renesas,pwm-r8a7778": for R-Car M1A
|
|
- "renesas,pwm-r8a7779": for R-Car H1
|
|
- "renesas,pwm-r8a7790": for R-Car H2
|
|
- "renesas,pwm-r8a7791": for R-Car M2-W
|
|
- "renesas,pwm-r8a7794": for R-Car E2
|
|
- "renesas,pwm-r8a7795": for R-Car H3
|
|
- reg: base address and length of the registers block for the PWM.
|
|
- #pwm-cells: should be 2. See pwm.txt in this directory for a description of
|
|
the cells format.
|
|
- clocks: clock phandle and specifier pair.
|
|
- pinctrl-0: phandle, referring to a default pin configuration node.
|
|
- pinctrl-names: Set to "default".
|
|
|
|
Example: R8A7790 (R-Car H2) PWM Timer node
|
|
|
|
pwm0: pwm@e6e30000 {
|
|
compatible = "renesas,pwm-r8a7790", "renesas,pwm-rcar";
|
|
reg = <0 0xe6e30000 0 0x8>;
|
|
#pwm-cells = <2>;
|
|
clocks = <&mstp5_clks R8A7790_CLK_PWM>;
|
|
pinctrl-0 = <&pwm0_pins>;
|
|
pinctrl-names = "default";
|
|
};
