[PATCH v2 0/2] Add driver for power button on Dell Wyse 3020

[Lubomir Rintel]

please consider applying the patches chained to this message. It's a
rather simple driver for a power button on Dell Ariel board along with
the Device Tree binding document.

Compared to previous version, endianness issues are fixed and I
connected a Reviewed-by for the binding doc that I failed to before.
Change logs are present in individual patches.

Note that this set is versioned "v2", but I've sent the previous version
(both unversioned) out twice before, because I've forgotten about
the previous submission before. Sorry if it caused a confusion.

Thank you
Lubo
