Re: [PATCH 1/2] dt-bindings: input: pm8941-pwrkey: Document wakeup-source property

The 'resin' keys (usually connected to a volume-down button) are
generally not supposed to wake up the device from suspend, so explicitly
document a wakeup-source property to enable this wakeup behavior.

For 'pwrkey' the default stays that pressing the button does wake up the
device from suspend.
