 * The Freescale i.MX27 integrates a complete keypad controller which may
 * be interfaced to a variety of matrix-style keypads up to 8x8 in size.  The
 * pins of this controller may also be driven as GPIOs, however they are not
 * routed via the IOMUX like the other GPIO devices, and hence this driver
 * exists to provide access to these GPIO pins.
