1Freescale i.MX PWM controller 2 3Required properties: 4- compatible : should be "fsl,<soc>-pwm" and one of the following 5 compatible strings: 6 - "fsl,imx1-pwm" for PWM compatible with the one integrated on i.MX1 7 - "fsl,imx27-pwm" for PWM compatible with the one integrated on i.MX27 8- reg: physical base address and length of the controller's registers 9- #pwm-cells: 2 for i.MX1 and 3 for i.MX27 and newer SoCs. See pwm.txt 10 in this directory for a description of the cells format. 11- clocks : Clock specifiers for both ipg and per clocks. 12- clock-names : Clock names should include both "ipg" and "per" 13See the clock consumer binding, 14 Documentation/devicetree/bindings/clock/clock-bindings.txt 15- interrupts: The interrupt for the pwm controller 16 17Example: 18 19pwm1: pwm@53fb4000 { 20 #pwm-cells = <3>; 21 compatible = "fsl,imx53-pwm", "fsl,imx27-pwm"; 22 reg = <0x53fb4000 0x4000>; 23 clocks = <&clks IMX5_CLK_PWM1_IPG_GATE>, 24 <&clks IMX5_CLK_PWM1_HF_GATE>; 25 clock-names = "ipg", "per"; 26 interrupts = <61>; 27}; 28
