Freescale i.MX PWM controller Required properties: - compatible: should be "fsl,<soc>-pwm" - reg: physical base address and length of the controller's registers - #pwm-cells: should be 2. The first cell specifies the per-chip index of the PWM to use and the second cell is the period in nanoseconds. - interrupts: The interrupt for the pwm controller Example: pwm1: pwm@53fb4000 { #pwm-cells = <2>; compatible = "fsl,imx53-pwm", "fsl,imx27-pwm"; reg = <0x53fb4000 0x4000>; interrupts = <61>; };
