Apalis TK1 GPIO Configuration

Hi,

I’m trying to re-configure the GPIO pins to fit our end application.

I’ve already re-mapped the pins as necessary in the tegra124-apalis-v1.2-gpio.dtsi file according to our hardware.

What I would like to know is, when I run cat /sys/kernel/debug/gpio, how can I change the label of the entries which appear in this list?

For reference, I’m using the Ubuntu L4T Easy Installer package as a starting point.

Thanks.

I believe in downstream this is, unfortunately, only possible programmatically during GPIO reservation e.g. as done here:

Ok, thanks @marcel.tx

You are very welcome.
