Re: passing function pointers through platform devices?

Thank you, but I've reorganized my system to pass platform resources to a
driver, which then registers simple gpio/pwm/quadencoder type devices as
standard classes declared in a subdirectory. Specific methods are then
simple exported by stackable drivers.
It's unlikely I will adopt the GPIO interface at this point unless they really
bring something new to the table.

I googled extensively and requested information on any current work here
before I began this project and got zip. (see forwarded email paste)

I also emailed Robert Schwebel directly and he told me to ask VGER as it was
being developed by someone else.

I don't mean to sound rude, but I really tried to build on existing work and
it wasn't made available, so I've gone my own way, I had not other choice.

P.S. Forgive my VGER newbness, but what is "-mm" ?

thx,
NZG
