[PATCH v4 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, it fixes a validation warning in the DT
bindings. Change logs are present in individual patches.

Thank you
Lubo
