When I did cat /sys/kernel/debug/gpio

below is the output i got.

GPIOs 0-31, platform/209c000.gpio, 209c000.gpio:

gpio-3   (tsc_X-              ) in  hi

gpio-9   (VSD_3V3             ) out lo

gpio-19  (2190000.usdhc cd    ) in  hi



GPIOs 32-63, platform/20a0000.gpio, 20a0000.gpio:



GPIOs 64-95, platform/20a4000.gpio, 20a4000.gpio:



GPIOs 96-127, platform/20a8000.gpio, 20a8000.gpio:

gpio-119 (?                   ) out lo



GPIOs 128-159, platform/20ac000.gpio, 20ac000.gpio:

gpio-131 (?                   ) out lo

gpio-132 (headset detect      ) in  lo

gpio-135 (spi32766.0          ) out lo

gpio-136 (?                   ) out lo

gpio-138 (spi4.14             ) out lo

gpio-139 (spi4.14             ) out lo



GPIOs 248-255, spi/spi32766.0, 74hc595, can sleep:


what does this mean??

I want to configure gpio1_IO00 pin as I/O. I will connect a switch. whenever a switch is pressed it should generate a interrupt. and it should servie the ISR.
