Subject[PATCH] I2C: BCM2835: Linking platform nodes to adapter nodes
In order to find I2C devices in the device tree, the platform nodes
have to be known by the I2C core. Analogous to the i2c-omap driver
this requires setting the dev.of_node parameter of the adapter.

I don't know if this is really necessary, but for me it does not work
without this line.
