| Freescale i.MX PWM controller |
| |
| Required properties: |
| - compatible : should be "fsl,<soc>-pwm" and one of the following |
| compatible strings: |
| - "fsl,imx1-pwm" for PWM compatible with the one integrated on i.MX1 |
| - "fsl,imx27-pwm" for PWM compatible with the one integrated on i.MX27 |
| - reg: physical base address and length of the controller's registers |
| - #pwm-cells: 2 for i.MX1 and 3 for i.MX27 and newer SoCs. See pwm.yaml |
| in this directory for a description of the cells format. |
| - clocks : Clock specifiers for both ipg and per clocks. |
| - clock-names : Clock names should include both "ipg" and "per" |
| See the clock consumer binding, |
| Documentation/devicetree/bindings/clock/clock-bindings.txt |
| - interrupts: The interrupt for the pwm controller |
| |
| Example: |
| |
| pwm1: pwm@53fb4000 { |
| #pwm-cells = <3>; |
| compatible = "fsl,imx53-pwm", "fsl,imx27-pwm"; |
| reg = <0x53fb4000 0x4000>; |
| clocks = <&clks IMX5_CLK_PWM1_IPG_GATE>, |
| <&clks IMX5_CLK_PWM1_HF_GATE>; |
| clock-names = "ipg", "per"; |
| interrupts = <61>; |
| }; |
