Kernel-3.10.0-957.el7_i2c-pnx

  • NXP PNX I2C Controller

Required properties:

  • reg: Offset and length of the register set for the device
  • compatible: should be “nxp,pnx-i2c”
  • interrupts: configure one interrupt line
  • #address-cells: always 1 (for i2c addresses)
  • #size-cells: always 0
  • interrupt-parent: the phandle for the interrupt controller that
    services interrupts for this device.

Optional properties:

  • clock-frequency: desired I2C bus clock frequency in Hz, Default: 100000 Hz

Examples:

i2c1: i2c@400a0000 {
    compatible = "nxp,pnx-i2c";
    reg = <0x400a0000 0x100>;
    interrupt-parent = <&mic>;
    interrupts = <51 0>;
    #address-cells = <1>;
    #size-cells = <0>;
};

i2c2: i2c@400a8000 {
    compatible = "nxp,pnx-i2c";
    reg = <0x400a8000 0x100>;
    interrupt-parent = <&mic>;
    interrupts = <50 0>;
    #address-cells = <1>;
    #size-cells = <0>;
    clock-frequency = <100000>;
};
