Re: What is the Purpose of GPIO Controller.

[krishna]

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
