I would agree that this should go in meta-oe.

I haven't implemented the new ioctl interface yet in libsoc and there is
no reason why there can't be two libraries with similar functionallity.

Cheers,
Jack.

 Since linux 4.8 the GPIO sysfs interface is deprecated.
 User space should use the character device instead.
 This library encapsulates the ioctl calls and data structures behind a
 straightforward API.

Agreed, the barrier for oe-core is high on purpose and I don't think this
is general purpose enough.  meta-oe is a perfect fit though.

As far as I know, libsoc is still being actively supported and if there's an 
API change, it should be fixed in no time. That's why I'm copying Jack here, 
who is an active OE developer here.

As of having an alternative for other potential users - there's nothing wrong 
with it. But, acceptance criteria into OE-Core is quite high, especially when 
there are alternative solutions already available. That's why I'm asking if 
it's any better than the other solution. In other words, why libgpiod should 
be accepted to OE-Core, but not libsoc? Maybe it should be submitted to 
meta-openembedded layer instead?

libsoc is fine but libgpiod will implement correctly gpio handling in
userspace as gpio sysfs is deprecated.
What is the problem to have libgpiod available for other potential
users? Thanks.

Not to derail your enthusiasm, but since this is being proposed for OE-Core, 
how is it better than libsoc by Jack Mitchell?

[OE-core] [PATCH] recipes-support: Add recipe for libgpiod

2017-05-11 Thread Marek Belisko 
libgpiod - C library and tools for interacting with the linux GPIO
character device

Since linux 4.8 the GPIO sysfs interface is deprecated.
User space should use the character device instead.
This library encapsulates the ioctl calls and data structures behind a
straightforward API.
