Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 7bit Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org 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
