Kernel-3.10.0-957.el7_imx-pw

Freescale i.MX PWM controller

Required properties:

  • compatible: should be “fsl,-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>;
};
