I2C for SiRFprimaII platforms Required properties : - compatible : Must be "sirf,prima2-i2c" - reg: physical base address of the controller and length of memory mapped region. - interrupts: interrupt number to the cpu. Optional properties: - clock-frequency : Constains desired I2C/HS-I2C bus clock frequency in Hz. The absence of the property indicates the default frequency 100 kHz. Examples : i2c0: i2c@b00e0000 { compatible = "sirf,prima2-i2c"; reg = <0xb00e0000 0x10000>; interrupts = <24>; };
