Amlogic Meson PWM Controller

============================



Required properties:

- compatible: Shall contain "amlogic,meson8b-pwm"

                         or "amlogic,meson-gxbb-pwm"

                         or "amlogic,meson-gxbb-ao-pwm"

                         or "amlogic,meson-axg-ee-pwm"

                         or "amlogic,meson-axg-ao-pwm"

                         or "amlogic,meson-g12a-ee-pwm"

                         or "amlogic,meson-g12a-ao-pwm-ab"

                         or "amlogic,meson-g12a-ao-pwm-cd"

- #pwm-cells: Should be 3. See pwm.yaml in this directory for a description of

  the cells format.



Optional properties:

- clocks: Could contain one or two parents clocks phandle for each of the two

  PWM channels.

- clock-names: Could contain at least the "clkin0" and/or "clkin1" names.



Example:



	pwm_ab: pwm@8550 {

		compatible = "amlogic,meson-gxbb-pwm";

		reg = <0x0 0x08550 0x0 0x10>;

		#pwm-cells = <3>;

		clocks = <&xtal>, <&xtal>;

		clock-names = "clkin0", "clkin1";
