Subject: [PATCH 3/3] arm/dt: Tegra: Add support-bit to SDHCI nodes
Date: Tue, 30 Aug 2011 13:17:17 -0600	[thread overview]
Message-ID: <1314731837-6985-3-git-send-email-swarren@nvidia.com> (raw)
In-Reply-To: <1314731837-6985-1-git-send-email-swarren@nvidia.com>

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.

This depends on patch 1 in this series. I assume Grant or Arnd will apply
them both to whatever branch usually takes .dts updates.
