Kernel-4.18.0-80.el8_i2c-efm32

• 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>;
    };
};
