* Renesas R-Car PWM Timer Controller
Required Properties:
pwm: pwm-rcar: Revise the device tree binding document about compatible The compatible should be "renesas,pwm-rcar", and one the the SoC specific string. So, this patch revises the documentation.

- 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";
