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 Cc: Johan Hovold Signed-off-by: Grygorii Strashko --- drivers/gpio/gpiolib.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/drivers/gpio/gpiolib.c b/drivers/gpio/gpiolib.c index 59eaa23..399ce2f 100644 --- a/drivers/gpio/gpiolib.c +++ b/drivers/gpio/gpiolib.c @@ -2259,7 +2259,8 @@ static void gpiolib_dbg_show(struct seq_file *s, struct gpio_chip *chip) int is_irq; for (i = 0; i < chip->ngpio; i++, gpio++, gdesc++) { - if (!test_bit(FLAG_REQUESTED, &gdesc->flags)) + if (!test_bit(FLAG_REQUESTED, &gdesc->flags) && + !test_bit(FLAG_USED_AS_IRQ, &gdesc->flags)) continue; gpiod_get_direction(gdesc); -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
