* 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>;
|
};
|
};
