+Amlogic Meson I2C controller
+
+Required properties:
+ - compatible: must be "amlogic,meson6-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).
+
+Examples:
+
+       i2c@c8100500 {
+               compatible = "amlogic,meson6-i2c";
+               reg = <0xc8100500 0x20>;
+               interrupts = <0 92 1>;
+               clocks = <&clk81>;
+               #address-cells = <1>;
+               #size-cells = <0>;
+       };
