OK, so given that I can't use basic_mmio_gpio and Alan thinks that
having an independent driver is the way to go anyway, is there any
chance to get my code reviewed and merged? I am using it since the day
I submitted it (one month ago), it appears to work fine for me, and
it is a mandatory piece to support SMBus multiplexing on many x86 server
boards. I'd like to see it happen in kernel 2.6.40.

I can resend the patch if it helps, but I did not make any change to
the code since the first submission.

Thanks,
