Hi Frank

Thanks for picking this up and asking for clarification. These pins are going to be used for a touch-screen interrupt, wakeup, and a GPS pulse per second.

ie Gumstix has chosen to label these pins as shown at gumstix.net.

Don,

The OMAP35x Applications Processor reference manual lists the alternate
function for gpio_0 as sys_nirq, so shouldn't pin 13 of the Summit
header be labeled "GPIO0_NIRQ" and not "GPIO0_WAKEUP"?  Also, from the
reference manual, the alternate function for gpio_114 is csi2_dx1, so
pin 4 of the summit header should be "GPIO114_CSI2_DX1", not
GPIO114_SPI1_NIRQ".  The labels for GPIO127_TS_IRQ and GPIO128_GPS_PPS
don't look right either.
