-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>;
- ...
