-From 81bf1ac05c1ba0d32db8fe8fb0cd52cb6b7d8e7e Mon Sep 17 00:00:00 2001
-From: Holger Freyther <zecke@openmoko.org>
-Date: Fri, 25 Jul 2008 23:06:05 +0100
-Subject: [PATCH] [neo] Every access to GPIO bank B has to go through the shadow code
-
- - Any setting of any PIN on bank B will undo the LED setting.
- Introduce neo1973_gpb_set_pin to set the PIN in a way not losing
- the LED or any other shadowed setting.
- - Update users of GPBXY for gta01 and gta02.
