Subject: [PATCH V4 3/5] omap3: board-3430sdp: Initialise the serial pads.
Date: Fri, 11 Mar 2011 11:34:45 +0530	[thread overview]
Message-ID: <1299823486-27192-2-git-send-email-r.sricharan@ti.com> (raw)
In-Reply-To: <1299823486-27192-1-git-send-email-r.sricharan@ti.com>

Use the mux framework to initialise the serial pads.

V1: Initial patch
V2: Remove flags that were to be used for only testing.
V3: Correct the off mode settings.
V4: Use the Macro to mux the static pads.
