+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";
