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>;
|
|
...
|
|
}
