Subject: Re: [PATCH] AMD Geode CS5535/5536 GPIO driver

Sorry, I'm just now getting around to looking at this.  Why did we move it
from cs553x-gpio.c to geode_32.c?  I have a lemote (longsoon-based) which
uses cs5536:

Linux debian 2.6.27.1 #193 Mon Jan 5 11:14:50 CST 2009 mips64 GNU/Linux

system type             : lemote-notebook

00:0e.7 USB Controller: Advanced Micro Devices [AMD] CS5536 [Geode companion] UOC (rev 02)

This leads me to believe that the gpio framework should not be
architecture-specific (nor geode-specific).
