Amlogic Meson I2C controller

Required properties:

 - compatible: must be:

	"amlogic,meson6-i2c" for Meson8 and compatible SoCs

	"amlogic,meson-gxbb-i2c" for GXBB and compatible SoCs

	"amlogic,meson-axg-i2c"for AXG and compatible SoCs

 - 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>

For details regarding the following core I2C bindings see also i2c.txt.

Optional properties:

- clock-frequency: the desired I2C bus clock frequency in Hz; in

  absence of this property the default value is used (100 kHz).

Examples:

	i2c@c8100500 {

		compatible = "amlogic,meson6-i2c";

		reg = <0xc8100500 0x20>;

		interrupts = <0 92 1>;

		clocks = <&clk81>;

		#address-cells = <1>;

		#size-cells = <0>;

	};
