Broadcom Kona PWM controller device tree bindings
This controller has 6 channels.
Required Properties :
- compatible: should contain "brcm,kona-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.yaml in this directory for a
description of the cells format.
Refer to clocks/clock-bindings.txt for generic clock consumer properties.
Example:
pwm: pwm@3e01a000 {
compatible = "brcm,bcm11351-pwm", "brcm,kona-pwm";
reg = <0x3e01a000 0xc4>;
clocks = <&pwm_clk>;
#pwm-cells = <3>;
};
