| |
Now GPIOs, wich are requested as IRQ only, will not be displayed through GPIO debugfs. For example: # cat /proc/interrupts CPU0 CPU1 ... 209: 0 0 4805d000.gpio 11 Edge 0-0021
# cat /debug/gpio ... GPIOs 160-191, platform/4805d000.gpio, gpio: <--- no info about gpio used as IRQ only here
GPIOs 192-223, platform/48051000.gpio, gpio: gpio-203 (vtt_fixed ) out hi ...
Hence, improve GPIO debugfs code to show such kind of GPIOs
After this patch sys/kernel/debug/gpio will produce following output:
# cat /debug/gpio ... GPIOs 160-191, platform/4805d000.gpio, gpio: gpio-171 ((null) ) in hi IRQ
GPIOs 192-223, platform/48051000.gpio, gpio: gpio-203 (vtt_fixed ) out hi
