Kernel-4.18.0-80.el8_i2c-lpc2k

NXP I2C controller for LPC2xxx/178x/18xx/43xx

Required properties:

  • compatible: must be “nxp,lpc1788-i2c”
  • reg: physical address and length of the device registers
  • interrupts: a single interrupt specifier
  • clocks: clock for the device
  • #address-cells: should be <1>
  • #size-cells: should be <0>

Optional properties:

  • clock-frequency: the desired I2C bus clock frequency in Hz; in
    absence of this property the default value is used (100 kHz).

Example:
i2c0: i2c@400a1000 {
compatible = “nxp,lpc1788-i2c”;
reg = <0x400a1000 0x1000>;
interrupts = <18>;
clocks = <&ccu1 CLK_APB1_I2C0>;
#address-cells = <1>;
#size-cells = <0>;
};

&i2c0 {
clock-frequency = <400000>;

lm75@48 {
    compatible = "nxp,lm75";
    reg = <0x48>;
};

};
