1 I2C for SiRFprimaII platforms
4 - compatible : Must be "sirf,prima2-i2c"
5 - reg: physical base address of the controller and length of memory mapped
7 - interrupts: interrupt number to the cpu.
10 - clock-frequency : Constains desired I2C/HS-I2C bus clock frequency in Hz.
11 The absence of the property indicates the default frequency 100 kHz.
16 compatible = "sirf,prima2-i2c";
17 reg = <0xb00e0000 0x10000>;
