| 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>;
| ...
| }
|
