+* NXP LPC18xx State Configurable Timer - Pulse Width Modulator driver
+
+Required properties:
+ - compatible: Should be "nxp,lpc1850-sct-pwm"
+ - reg: Should contain physical base address and length of pwm registers.
+ - clocks: Must contain an entry for each entry in clock-names.
+ See ../clock/clock-bindings.txt for details.
+ - clock-names: Must include the following entries.
+ - pwm: PWM operating clock.
+ - #pwm-cells: Should be 3. See pwm.txt in this directory for the description
+ of the cells format.
+
+Example:
+ pwm: pwm@40000000 {
+ compatible = "nxp,lpc1850-sct-pwm";
+ reg = <0x40000000 0x1000>;
+ clocks =<&ccu1 CLK_CPU_SCT>;
+ clock-names = "pwm";
+ #pwm-cells = <3>;
+ };
