Kernel-4.18.0-80.el8_i2c-xlp9xx

Device tree configuration for the I2C controller on the XLP9xx/5xx SoC

Required properties:

• compatible : should be “netlogic,xlp980-i2c”
• reg : bus address start and address range size of device
• interrupts : interrupt number

Optional properties:

• clock-frequency : frequency of bus clock in Hz

                Defaults to 100 KHz when the property is not specified
  

Example:

i2c0: i2c@113100 {
compatible = “netlogic,xlp980-i2c”;
#address-cells = <1>;
#size-cells = <0>;
reg = <0 0x113100 0x100>;
clock-frequency = <400000>;
interrupts = <30>;
interrupt-parent = <&pic>;
};
