Well, that's me ! I am aware it sounds crazy. However, the registers on
the pmic are not memory mapped and the access is done via SPI.
The pmic manuals (MC13783, MC13892,) describe the SPI frame (ok, frame
is probably a big word..it is only a 32 bit) and one of the field is the
internal register number.

Using a structure looks like to me even stranger. We have to use some
kind of offsetof() to get the index number back and put it inside the
SPI data.

Best regards,
Stefano Babic
