Robert,
Another thought: What is your kernel version, and what is your i2c controller ?
SMBus support was added to regmap only recently, so if your controller only
supports SMBus (not raw i2c transactions), and you have an older kernel,
this might not work. The driver should fail to instantiate in that case,
though, if I recall correctly.
Thanks,
Guenter
