0001 Marvell PWM controller
0002
0003 Required properties:
0004 - compatible: should be one or more of:
0005 - "marvell,pxa250-pwm"
0006 - "marvell,pxa270-pwm"
0007 - "marvell,pxa168-pwm"
0008 - "marvell,pxa910-pwm"
0009 - reg: Physical base address and length of the registers used by the PWM channel
0010 Note that one device instance must be created for each PWM that is used, so the
0011 length covers only the register window for one PWM output, not that of the
0012 entire PWM controller. Currently length is 0x10 for all supported devices.
0013 - #pwm-cells: Should be 1. This cell is used to specify the period in
0014 nanoseconds.

0016 Example PWM device node:
0017
0018 pwm0: pwm@40b00000 {
0019 compatible = "marvell,pxa250-pwm";
0020 reg = <0x40b00000 0x10>;
0021 #pwm-cells = <1>;
0022 };
0023
0024 Example PWM client node:
0025
0026 backlight {
0027 compatible = "pwm-backlight";
0028 pwms = <&pwm0 5000000>;
0029 ...
0030 }
