From 6111d50c5885f6ba00dc935e44bcbbcd63b3915d Mon Sep 17 00:00:00 2001 From: Stephen Warren Date: Tue, 20 Sep 2011 10:46:26 -0600 Subject: [PATCH] arm/dt: Tegra: Add support-8bit to SDHCI nodes For Seaboard's internal eMMC, this makes the difference between a 5.5MB/s and 10.2MB/s transfer rate. On Harmony, there wasn't any measurable difference on my cheap/slow ~2MB/s card.
