1Freescale i.MX PWM controller 2 3Required properties: 4- compatible: should be "fsl,<soc>-pwm" 5- reg: physical base address and length of the controller's registers 6- #pwm-cells: should be 2. The first cell specifies the per-chip index 7 of the PWM to use and the second cell is the period in nanoseconds. 8- interrupts: The interrupt for the pwm controller 9 10Example: 11 12pwm1: pwm@53fb4000 { 13 #pwm-cells = <2>; 14 compatible = "fsl,imx53-pwm", "fsl,imx27-pwm"; 15 reg = <0x53fb4000 0x4000>; 16 interrupts = <61>; 17}; 18
