| * 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>; |
| }; |
| }; |
