-Marvell PWM controller
-
-Required properties:
-- compatible: should be one or more of:
-  - "marvell,pxa250-pwm"
-  - "marvell,pxa270-pwm"
-  - "marvell,pxa168-pwm"
-  - "marvell,pxa910-pwm"
-- reg: Physical base address and length of the registers used by the PWM channel
-  Note that one device instance must be created for each PWM that is used, so the
-  length covers only the register window for one PWM output, not that of the
-  entire PWM controller.  Currently length is 0x10 for all supported devices.
-- #pwm-cells: Should be 1.  This cell is used to specify the period in
-  nanoseconds.
-
-Example PWM device node:
-
-pwm0: pwm@40b00000 {
-	compatible = "marvell,pxa250-pwm";
-	reg = <0x40b00000 0x10>;
-	#pwm-cells = <1>;
-};
-
-Example PWM client node:
-
-backlight {
-	compatible = "pwm-backlight";
-	pwms = <&pwm0 5000000>;
-	...
-}
