Hi Ian,
Thank you very much.
My doubt is,
I have a board here where all lines to the peripherals are highly
multiplexed and
I had to configure these lines. Now my Wireless Ethernet Driver has
a conflict with
the audiocodec driver. What I mean is, if I load the WLAN driver and
try to load the
audiocodec driver next, the audiocodec driver is not responding.
I traced the bug to be sharing of GPIO Lines.
Form your mail I understand GPIO controller serves some Hardware
designers purpose.
But what _purpose_ is it serving a _programmer_.
Regards,
Krishna Chaitanya
