-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.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@18031000 {
-	compatible = "brcm,iproc-pwm";
-	reg = <0x18031000 0x28>;
-	clocks = <&osc>;
-	#pwm-cells = <3>;
-};
