| 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>; |
| ... |
| } |
