-
-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.yaml 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>;
-  };
