Subject: [PATCH 9/13] powerpc: Create Marvell mv64x60 I2C platform_data
Date: Fri, 4 May 2007 14:08:26 -0700 [thread overview]
Message-ID: <20070504210826.GC3166@xyzzy.farnsworth.org> (raw)
In-Reply-To: <20070502214416.GD27253@xyzzy.farnsworth.org>
This patch creates platform_device entries for the Marvell mv64x60
I2C ports, based on information contained in device tree.
Signed-off-by: Dale Farnsworth <dale@farnsworth•org>
