The BCM2835 has 3 identical I2C controllers. Instantiate them all in the SoC .dtsi file, and enable the relevant two in the Raspberry Pi board .dts file. Note that on the Raspberry Pi Model B revision 1, I2C0 is connected to the general-purpose expansion header, and I2C1 is connected to the camera connector. Revision 2 of the board swaps these assignments:-( Signed-off-by: Stephen Warren <swarren@wwwdotorg.org>
