1Atmel PWM controller 2 3Required properties: 4 - compatible: should be one of: 5 - "atmel,at91sam9rl-pwm" 6 - "atmel,sama5d3-pwm" 7 - "atmel,sama5d2-pwm" 8 - reg: physical base address and length of the controller's registers 9 - #pwm-cells: Should be 3. See pwm.txt in this directory for a 10 description of the cells format. 11 12Example: 13 14 pwm0: pwm@f8034000 { 15 compatible = "atmel,at91sam9rl-pwm"; 16 reg = <0xf8034000 0x400>; 17 #pwm-cells = <3>; 18 }; 19 20 pwmleds { 21 compatible = "pwm-leds"; 22 23 d1 { 24 label = "d1"; 25 pwms = <&pwm0 3 5000 0> 26 max-brightness = <255>; 27 }; 28 29 d2 { 30 label = "d2"; 31 pwms = <&pwm0 1 5000 1> 32 max-brightness = <255>; 33 }; 34 }; 35
