+* Energymicro efm32 i2c controller
+
+Required properties :
+
+ - reg : Offset and length of the register set for the device
+ - compatible : should be "energymicro,efm32-i2c"
+ - interrupts : the interrupt number
+ - clocks : reference to the module clock
+
+Recommended properties :
+
+ - clock-frequency : maximal I2C bus clock frequency in Hz.
+ - energymicro,location : Decides the location of the USART I/O pins.
+   Allowed range : [0 .. 6]
+
+Example:
+	i2c0: i2c@4000a000 {
+		#address-cells = <1>;
+		#size-cells = <0>;
+		compatible = "energymicro,efm32-i2c";
+		reg = <0x4000a000 0x400>;
+		interrupts = <9>;
+		clocks = <&cmu clk_HFPERCLKI2C0>;
+		clock-frequency = <100000>;
+		status = "ok";
+		energymicro,location = <3>;
+
+		eeprom@50 {
+			compatible = "microchip,24c02";
+			reg = <0x50>;
+			pagesize = <16>;
+		};
