| 2 | |
| 3 | Required properties: |
| 4 | - compatible: should be one of: |
| 5 | - "st,spear320-pwm" |
| 6 | - "st,spear1340-pwm" |
| 7 | - reg: physical base address and length of the controller's registers |
| 8 | - #pwm-cells: number of cells used to specify PWM which is fixed to 2 on |
| 9 | SPEAr. The first cell specifies the per-chip index of the PWM to use and |
| 10 | the second cell is the period in nanoseconds. |
| 11 | |
| 12 | Example: |
| 13 | |
| 14 | pwm: pwm@a8000000 { |
| 15 | compatible ="st,spear320-pwm"; |
| 16 | reg = <0xa8000000 0x1000>; |
| 17 | #pwm-cells = <2>; |
| 18 | }; |
