from the git tree. This merges a lot that we're not using, but there's too many files to be selective and have a hope of catching everything. If there are conflicts with the rest of the tree, we'll resolve them on a case by case basis. MFC after: 2 weeks Sponsored by: Netflix, Inc.

* 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!
