1* Energymicro efm32 i2c controller
2
3Required properties :
4
5 - reg : Offset and length of the register set for the device
6 - compatible : should be "energymicro,efm32-i2c"
7 - interrupts : the interrupt number
8 - clocks : reference to the module clock
9
10Recommended properties :
11
12 - clock-frequency : maximal I2C bus clock frequency in Hz.
13 - energymicro,location : Decides the location of the USART I/O pins.
14   Allowed range : [0 .. 6]

16Example:
17	i2c0: i2c@4000a000 {
18		#address-cells = <1>;
19		#size-cells = <0>;
20		compatible = "energymicro,efm32-i2c";
21		reg = <0x4000a000 0x400>;
22		interrupts = <9>;
23		clocks = <&cmu clk_HFPERCLKI2C0>;
24		clock-frequency = <100000>;
25		energymicro,location = <3>;

27		eeprom@50 {
28			compatible = "microchip,24c02";
29			reg = <0x50>;
30			pagesize = <16>;
31		};
