43 can be routed from GPIO19 of the GPIO controller.
45 To better understand the change from PXA25x/PXA27x GPIO alternate function
48   1. GPIO controller on PXA3xx is now a dedicated controller, same as other
50      which can be routed to external through one or more MFPs (e.g. GPIO<0>
54   2. Alternate function configuration is removed from this GPIO controller,
55      the remaining functions are pure GPIO-specific, i.e.
57        - GPIO signal level control
58        - GPIO direction control
59        - GPIO level change detection

68 NOTE: with such a clear separation of MFP and GPIO, by GPIO<xx> we normally
69 mean it is a GPIO signal, and by MFP<xxx> or pin xxx, we mean a physical
