From 3e7d83bc96d59013792e5546e7832668d3adbce7 Mon Sep 17 00:00:00 2001 From: Michael Chan <mchan@broadcom.com> Date: Thu, 21 Apr 2005 17:10:36 -0700 Subject: [PATCH] [TG3]: Add GPIO3 for 5752 Add bit definitions for the new GPIO3 in 5752. GPIO3 must be driven as output when it is unused. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S.
