+* Amlogic Meson I2C controller
+
+Required properties:
+ - compatible: must be "amlogic,meson6-i2c"
+ - reg: physical address and length of the device register set
+ - 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:
+
+ i2c@c1108500 {
+ compatible = "amlogic,meson6-i2c";
+ reg = <0xc1108500 0x20>;
+ interrupts = <0 21 1>;
+ clocks = <&clk81>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+ };
