Subject: [PATCH 08/14] omap3630: Configure HSMMC1 to 4-bit
Date: Thu, 12 Nov 2009 16:08:47 -0800 [thread overview]
Message-ID: <20091113000847.9034.90009.stgit@localhost> (raw)
In-Reply-To: <20091113000444.9034.41293.stgit@localhost>
From: Madhu <madhu.cr@ti.com>
The HSMMC1 controller on omap3630 supprts only 4-bit mode. If cpu
is 3630 configure HSMMC1 wires to 4-bit.
