Re: Regarding export of GPIOs

Hi Kent,
Thank you for your response.

I am observing a strange thing here.

The kernel logs for the hogged GPIO reports as:
[    0.251788] GPIO line <num> (name) hogged as output/high

The corresponding dts changes are:
>
> pNum {
> gpio-hog;
> gpios = <num GPIO_ACTIVE_LOW>;
> output-low;
> line-name = "name";
> };


Based on the kernel log, I could say that it is hogging the GPIO as expected.

But using the gpioinfo and lsgpio tools always show the direction as
"input" for the hogged GPIO.
gpioinfo <chipname>:
line  X:      "pX" "name"   input   active-low [used]

lsgpio -n <chipname>:
line X: "pX" "name" [kernel active-low]

I tried following the kernel by adding some logs, it seems to set the
correct direction.
I have really ran out of options here, any leads would be helpful.

Thanks
