+description: |
+ This GPIO controller is found in the Intel IXP4xx
+ processors. It supports 16 GPIO lines.
+ The interrupt portions of the GPIO controller is hierarchical.
+ The synchronous edge detector is part of the GPIO block, but the
+ actual enabling/disabling of the interrupt line is done in the
+ main IXP4xx interrupt controller which has a 1-to-1 mapping for
+ the first 12 GPIO lines to 12 system interrupts.
+ The remaining 4 GPIO lines can not be used for receiving
+ interrupts.
+ The interrupt parent of this GPIO controller must be the
+ IXP4xx interrupt controller.
+ GPIO 14 and 15 can be used as clock outputs rather than GPIO,
+ and this can be enabled by a special flag.
