Kernel-4.18.0-80.el8_i2c-jz4780

• Ingenic JZ4780 I2C Bus controller

Required properties:

• compatible: should be “ingenic,jz4780-i2c”
• reg: Should contain the address & size of the I2C controller registers.
• interrupts: Should specify the interrupt provided by parent.
• clocks: Should contain a single clock specifier for the JZ4780 I2C clock.
• clock-frequency: desired I2C bus clock frequency in Hz.

Recommended properties:

• pinctrl-names: should be “default”;
• pinctrl-0: phandle to pinctrl function

Optional properties:

• interrupt-parent: Should be the phandle of the interrupt controller that
  delivers interrupts to the I2C block.

Example

/ {
i2c4: i2c4@10054000 {
compatible = “ingenic,jz4780-i2c”;
reg = <0x10054000 0x1000>;

    interrupt-parent = <&intc>;
    interrupts = <56>;

    clocks = <&cgu JZ4780_CLK_SMB4>;
    clock-frequency = <100000>;
    pinctrl-names = "default";
    pinctrl-0 = <&pins_i2c4_data>;

};
