[fedora-arm] Re: Help testing suspend on arm

TBH I'm not particular surprised to see this, I'm aware it works for
some aarch64 devices but I've not had the time to focus on anything
around suspend because well making/keeping things booting and the
basics takes up a lot of my time.

This good information, would you be able to assist in documenting this
in a wiki page. I've created an initial template [1] so feel free to
add/adjust.

Has this been reported to the pxa_gpio driver maintainer upstream?
Without that the above bug report will sit until I have the time to
deal with it so it's unlikely to go too far. Please feel free to cc:
on emails if it will assist with accelerating fixes.

I'm very sure that is the case.
