1*4882a593SmuzhiyunI2C for SiRFprimaII platforms
2*4882a593Smuzhiyun
3*4882a593SmuzhiyunRequired properties :
4*4882a593Smuzhiyun- compatible : Must be "sirf,prima2-i2c"
5*4882a593Smuzhiyun- reg: physical base address of the controller and length of memory mapped
6*4882a593Smuzhiyun     region.
7*4882a593Smuzhiyun- interrupts: interrupt number to the cpu.
8*4882a593Smuzhiyun
9*4882a593SmuzhiyunOptional properties:
10*4882a593Smuzhiyun- clock-frequency : Constains desired I2C/HS-I2C bus clock frequency in Hz.
11*4882a593Smuzhiyun  The absence of the property indicates the default frequency 100 kHz.
