Other than the binding and wanting to use the standard ->set_mode
Also, in this particular case, the bindings are not standardized, and
there's a good chance that whatever new platform uses a similar device
will need to do something slightly different.
Yeah, everyone else will do the sane thing, and describe
the two register ranges the IDE uses, not a much big

Easier to use pata_platform I would think ? Just create the OF device and
bind it to pata_platform.

Glue code to hook up the pata_platform on the PA Semi Electra eval board.
CFE sets up device tree entries for the IDE interface, with device type
'ide' and compatible field 'electra-ide'.
We unfortunately need to modify the resources before calling the generic
platform driver, since the device tre
