Berlin PWM controller
Required properties:
- compatible: should be "marvell,berlin-pwm"
- reg: physical base address and length of the controller's registers
- clocks: phandle to the input clock
- #pwm-cells: should be 3. See pwm.txt in this directory for a description of
the cells format.
Example:
pwm: pwm@f7f20000 {
compatible = "marvell,berlin-pwm";
reg = <0xf7f20000 0x40>;
clocks = <&chip_clk CLKID_CFG>;
#pwm-cells = <3>;
}
