7 title: Intel IXP4xx XScale Networking Processors GPIO Controller
10   This GPIO controller is found in the Intel IXP4xx
11   processors. It supports 16 GPIO lines.
12   The interrupt portions of the GPIO controller is hierarchical.
13   The synchronous edge detector is part of the GPIO block, but the
15   main IXP4xx interrupt controller which has a 1-to-1 mapping for
16   the first 12 GPIO lines to 12 system interrupts.
17   The remaining 4 GPIO lines can not be used for receiving
19   The interrupt parent of this GPIO controller must be the
20   IXP4xx interrupt controller.
21   GPIO 14 and 15 can be used as clock outputs rather than GPIO,
