Subject: [PATCH v8 4/4] powerpc: doc/dts-bindings: update doc of FSL I2C bindings
Date: Wed, 17 Feb 2010 11:19:20 +0100	[thread overview]
Message-ID: <1266401960-19127-5-git-send-email-wg@grandegger.com> (raw)
In-Reply-To: <1266401960-19127-4-git-send-email-wg-5Yr1BZd7O62+XT7JhA+gdA@public.gmane.org>

From: Wolfgang Grandegger <wg-ynQEQJNshbs@public.gmane.org>

This patch adds the MPC5121 to the list of supported devices,
enhances the doc of the "clock-frequency" property and removes
the obsolete "cell-index", "device_type" and "fsl-i2c" property.
Furthermore an example for the MPC5121 has been added.
