-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.yaml 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>;
