Drop #address-cells and #size-cells, which are not required by the
gpio-keys binding documentation, as button sub-nodes are not devices.

FYI, with "[PATCH] scripts/dtc: Update to upstream version 53bf130b1cdd":
(http://www.spinics.net/lists/devicetree/msg117206.html) applied:

Warning (unit_address_vs_reg): Node /keyboard/button at 21 has a unit
name, but no reg property

Hi Andreas,
This means you can also drop the unit-address (the @21 part) for the button.
What about using a more relevant name like "key_up" instead of "button"?
