Atmel PWM controller
Required properties:
- compatible: should be one of:
- "atmel,at91sam9rl-pwm"
- "atmel,sama5d3-pwm"
- reg: physical base address and length of the controller's registers
- #pwm-cells: Should be 3. See pwm.txt in this directory for a
description of the cells format.
Example:
pwm0: pwm@f8034000 {
compatible = "atmel,at91sam9rl-pwm";
reg = <0xf8034000 0x400>;
#pwm-cells = <3>;
};
pwmleds {
compatible = "pwm-leds";
d1 {
label = "d1";
pwms = <&pwm0 3 5000 0>
max-brightness = <255>;
};
d2 {
label = "d2";
pwms = <&pwm0 1 5000 1>
max-brightness = <255>;
};
};
