The I2C controller node needs #address-cells and #size-cells properties, but these are currently missing. Add them. This allows child nodes to be parsed correctly. Cc: stable@vger.kernel.org Signed-off-by: Stephen Warren <swarren@wwwdotorg.org> Signed-off-by: Olof Johansson <olof@lixom.net>

* The GPIO IP block is designed for 3 banks of GPIOs.

|
* Each bank has a GPIO interrupt for itself.
|
|
* There is an overall "any bank" interrupt.
|
|
* In order, these are GIC interrupts 17, 18, 19, 20.
|
|
* Since the BCM2835 only has 2 banks, the 2nd bank
|
|
* interrupt output appears to be mirrored onto the
|
|
* 3rd bank's interrupt signal.
|
|
* So, a bank0 interrupt shows up on 17, 20, and
|
|
* a bank1 interrupt shows up on 18, 19, 20!
