| 3 | Required properties: |
| 4 | - compatible: Should be "img,pistachio-pwm" |
| 5 | - reg: Should contain physical base address and length of pwm registers. |
| 6 | - clocks: Must contain an entry for each entry in clock-names. |
| 7 | See ../clock/clock-bindings.txt for details. |
| 8 | - clock-names: Must include the following entries. |
| 9 | - pwm: PWM operating clock. |
| 10 | - sys: PWM system interface clock. |
| 11 | - #pwm-cells: Should be 2. See pwm.yaml in this directory for the |
| 12 | description of the cells format. |
| 13 | - img,cr-periph: Must contain a phandle to the peripheral control |
| 14 | syscon node which contains PWM control registers. |
| 15 | |
| 16 | Example: |
| 17 | pwm: pwm@18101300 { |
| 18 | compatible = "img,pistachio-pwm"; |
| 19 | reg = <0x18101300 0x100>; |
| 20 | clocks = <&pwm_clk>, <&system_clk>; |
| 21 | clock-names = "pwm", "sys"; |
| 22 | #pwm-cells = <2>; |
| 23 | img,cr-periph = <&cr_periph>; |
| 24 | }; |
