+
Required properties:
5
+
- compatible: Shall contain "amlogic,meson8b-pwm" or "amlogic,meson-gxbb-pwm".
6
+
- #pwm-cells: Should be 3. See pwm.txt in this directory for a description of
7
+
the cells format.

+
Optional properties:
10
+
- clocks: Could contain one or two parents clocks phandle for each of the two
11
+
PWM channels.
12
+
- clock-names: Could contain at least the "clkin0" and/or "clkin1" names.

+
16
+
pwm_ab: pwm@8550 {
17
+
compatible = "amlogic,meson-gxbb-pwm";
18
+
reg = <0x0 0x08550 0x0 0x10>;
19
+
#pwm-cells = <3>;
20
+
status = "disabled";
21
+
clocks = <&xtal>, <&xtal>;
22
+
clock-names = "clkin0", "clkin1";
