|
|
|
|
Required properties:
|
|
- compatible: Should be "img,pistachio-pwm"
|
|
- reg: Should contain physical base address and length of pwm registers.
|
|
- clocks: Must contain an entry for each entry in clock-names.
|
|
See ../clock/clock-bindings.txt for details.
|
|
- clock-names: Must include the following entries.
|
|
- pwm: PWM operating clock.
|
|
- sys: PWM system interface clock.
|
|
- #pwm-cells: Should be 2. See pwm.txt in this directory for the
|
|
description of the cells format.
|
|
- img,cr-periph: Must contain a phandle to the peripheral control
|
|
syscon node which contains PWM control registers.
|
|
|
|
Example:
|
|
pwm: pwm@18101300 {
|
|
compatible = "img,pistachio-pwm";
|
|
reg = <0x18101300 0x100>;
|
|
clocks = <&pwm_clk>, <&system_clk>;
|
|
clock-names = "pwm", "sys";
|
|
#pwm-cells = <2>;
|
|
img,cr-periph = <&cr_periph>;
|
|
};
