Subject: [PATCH 1/3] i.MX51: handle IRQ for gpio 16..31
Date: Tue, 20 Jul 2010 09:16:12 +0200	[thread overview]
Message-ID: <1279610174-6025-1-git-send-email-eric@eukrea.com> (raw)

The i.MX51 generates 2 IRQ for each GPIO bank : one for gpio 0 to 15
and one for gpio 16 to 31.
Actually only the lower IRQ is registered so register the second one.
