   2  * include/asm-arm/arch-pxa/h2200-gpio.h
   3  * History:
   4  *
   5  * 2003-12-08 Jamey Hicks               Copied over h22xx gpio definitions and beginnings of h22xx (hamcop) asic declarations
   6  * 2004-01-26 Michael Opdenacker        Replaced "_H5200_GPIO_H_" by "_H2200_GPIO_H_"
   7  *                                      Added definition for IRQ_GPIO_H2200_ASIC_INT (like in h5400-gpio.h)
   8  * 2004-02-05 Koen Kooi                 Added definition for IRQ_NR_H2200_CF_DETECT_N
