Embedded PPC has followed in ARMs footsteps with the use of platform_data for board specific information to be passed to drivers. The plan is to grow its use in embedded PPC. It would seem introducing a new field for ACPI information would be the least painful solution. Can some clarify what kind of information ACPI needs. I'm asking because firmware_data does not seem any more clear to me. Also, we should really probably be a bit more specific in Documentation/driver-model/device.txt once we decide the meaning of the fields is, possible giving an example. - kumar On Jan 11, 2005, at 11:15 PM, Li Shaohua wrote: > On Wed, 2005-01-12 at 13:06, Greg KH wrote: > > > > > If we are doing things incorrectly, I am not argueing that our > usage > > > has to the way it sits.
