-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 at 8550 {
- compatible = "amlogic,meson-gxbb-pwm";
- reg = <0x0 0x08550 0x0 0x10>;
- #pwm-cells = <3>;
- clocks = <&xtal>, <&xtal>;
- clock-names = "clkin0", "clkin1";
- }
