-Freescale MXS PWM controller

-Required properties:
-- compatible: should be "fsl,imx23-pwm"
-- reg: physical base address and length of the controller's registers
-- #pwm-cells: should be 3. See pwm.yaml in this directory for a description of
- the cells format.
-- fsl,pwm-number: the number of PWM devices

-Example:
-
-pwm: pwm@80064000 {
- compatible = "fsl,imx28-pwm", "fsl,imx23-pwm";
- reg = <0x80064000 0x2000>;
- #pwm-cells = <3>;
- fsl,pwm-number = <8>;
