Subject: [PATCH v2 2/7] msm: Remove chip-ifdefs for GPIO io mappings
Date: Fri,  3 Jun 2011 15:44:14 -0700	[thread overview]
Message-ID: <1307141059-22431-3-git-send-email-davidb@codeaurora.org> (raw)
In-Reply-To: <1307141059-22431-1-git-send-email-davidb@codeaurora.org>

The two GPIO controllers are always mapped to the same virtual address
across all MSM devices.  Instead of selecting this at compile time,
determine the physical address at runtime, eliminating yet something
else preventing multiple MSM targets from being compiled into the same
kernel.
