1 | Atmel PWM controller | ||
2 | |||
3 | Required properties: | ||
4 | - compatible: should be one of: | ||
5 | - "atmel,at91sam9rl-pwm" | ||
6 | - "atmel,sama5d3-pwm" | ||
7 | - reg: physical base address and length of the controller's registers | ||
8 | - #pwm-cells: Should be 3. See pwm.txt in this directory for a | ||
9 | description of the cells format. | ||

11 | Example: | ||

13 | pwm0: pwm@f8034000 { | ||
14 | compatible = "atmel,at91sam9rl-pwm"; | ||
15 | reg = <0xf8034000 0x400>; | ||
16 | #pwm-cells = <3>; | ||
