Subject: [PATCH 3/5] arm/dt: tegra: Fix I2C nodes to match board files
Date: Mon, 21 Nov 2011 14:44:09 -0700	[thread overview]
Message-ID: <1321911851-10091-3-git-send-email-swarren@nvidia.com> (raw)
In-Reply-To: <1321911851-10091-1-git-send-email-swarren@nvidia.com>

With board files, all I2C busses run at 400KHz. Fix the device-tree
to be consistent with this. It's possible this is incorrect, but at
least it keeps the board files and device-tree consistent.

Also, disable any I2C controllers that the board files don't register,
also for consistency.
