Subject: [U-Boot] [PATCH] OMAP3: Overo: Update GPMC timing for ethernet chip.
Date: Wed,  7 Sep 2011 07:57:49 -0400	[thread overview]
Message-ID: <1315396670-22889-2-git-send-email-philip@opensdr.com> (raw)
In-Reply-To: <1315396670-22889-1-git-send-email-philip@opensdr.com>

The existing timing does not quite meet the minimum requirements
in the LAN9221 datasheet. The timing in this patch solves problems
noticed on some parts.
