Subject: [PATCH 1/7] mfd: pcf50633 disable unnecessary shutdown on lowsys
Date: Wed, 14 Oct 2009 02:12:30 +0400 [thread overview]
Message-ID: <1255471956-29201-1-git-send-email-fercerpav@gmail.com> (raw)
On gta02 hardware revision A5 it can actually bring the system down
during normal operating conditions so we disable it.
