+Amlogic Meson PWM Controller
+=================================
+
+Required properties:
+- compatible: Shall contain "amlogic,meson8b-pwm" or "amlogic,meson-gxbb-pwm".
+- #pwm-cells: Should be 3. See pwm.txt 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>;
+	status = "disabled";
+	clocks = <&xtal>, <&xtal>;
+	clock-names = "clkin0", "clkin1";
+}
