Subject: [PATCH 3/6] of/of_i2c: add support for dedicated OF I2C devices
Date: Tue, 28 Oct 2008 20:46:15 +0300	[thread overview]
Message-ID: <20081028174615.GC25349@oksana.dev.rtsoft.ru> (raw)
In-Reply-To: <20081028174532.GA23834@oksana.dev.rtsoft.ru>

of_i2c will create the OF platform device if it knows that the
device won't work without platform data. The OF platform driver
will fill the platform data and will register real I2C device.
