Same answer as here, though: http://www.spinics.net/lists/linux-i2c/msg17001.html > +#define TANGOX_I2C_CONFIG 0x00 > +#define TANGOX_I2C_CLKDIV 0x04 > +#define TANGOX_I2C_DEVADDR 0x08 > +#define TANGOX_I2C_ADDR 0x0c > +#define TANGOX_I2C_DATAOUT 0x10 > +#define TANGOX_I2C_DATAIN 0x14 > +#define TANGOX_I2C_STATUS 0x18 > +#define TANGOX_I2C_STARTXFER 0x1c > +#define TANGOX_I2C_BYTECNT 0x20 > +#define TANGOX_I2C_INT_EN 0x24 > +#define TANGOX_I2C_INT_STAT 0x28 The register set looks like the one from i2c-xlr.c, only that they are 32 bit apart instead of 8. Can you check if you can reuse that driver? Thanks, Wolfram
