Re: [beagleboard] sysfs gpio deprecated?

The sysfs gpio ABI will be removed from the Linux kernel in 2020. The new ABI uses a character device to represent each gpiochip. libgpiod started by Bartosz Golaszewski is a good way for userspace code to use the the new ABI: https://git.kernel.org/pub/scm/libs/libgpiod/libgpiod.git/about/

[beagleboard] sysfs gpio deprecated?

Hi, I've started looking at the sysfs gpio interface and saw some notes that it's considered obsolete and deprecated. I'm looking for a good pointer to the ABI (?) character driver interface for gpio. I'll probably find one right after posting this. :) In case I'm not using the right
