* Renesas R-Car PWM Timer Controller
Required Properties:
- compatible: should be "renesas,pwm-rcar" and one of the following.
- "renesas,pwm-r8a7743": for RZ/G1M
- "renesas,pwm-r8a7744": for RZ/G1N
- "renesas,pwm-r8a7745": for RZ/G1E
- "renesas,pwm-r8a774a1": for RZ/G2M
- "renesas,pwm-r8a774c0": for RZ/G2E
- "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
- "renesas,pwm-r8a7796": for R-Car M3-W
- "renesas,pwm-r8a77965": for R-Car M3-N
- "renesas,pwm-r8a77970": for R-Car V3M
- "renesas,pwm-r8a77980": for R-Car V3H
- "renesas,pwm-r8a77990": for R-Car E3
- "renesas,pwm-r8a77995": for R-Car D3
- 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: R8A7743 (RZ/G1M) PWM Timer node
pwm0: pwm@e6e30000 {
compatible = "renesas,pwm-r8a7743", "renesas,pwm-rcar";
reg = <0 0xe6e30000 0 0x8>;
clocks = <&cpg CPG_MOD 523>;
power-domains = <&sysc R8A7743_PD_ALWAYS_ON>;
resets = <&cpg 523>;
#pwm-cells = <2>;
pinctrl-0 = <&pwm0_pins>;
pinctrl-names = "default";
};
