* 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>;
energymicro,location = <3>;
eeprom@50 {
compatible = "microchip,24c02";
reg = <0x50>;
pagesize = <16>;
};
};
