Broadcom iProc PWM controller device tree bindings
This controller has 4 channels.
Required Properties :
- compatible: must be "brcm,iproc-pwm"
- reg: physical base address and length of the controller's registers
- clocks: phandle + clock specifier pair for the external clock
- #pwm-cells: Should be 3. See pwm.txt in this directory for a
description of the cells format.
Refer to clocks/clock-bindings.txt for generic clock consumer properties.
Example:
pwm: pwm@18031000 {
compatible = "brcm,iproc-pwm";
reg = <0x18031000 0x28>;
clocks = <&osc>;
#pwm-cells = <3>;
};
