This series adds support for the Embedded Controller which is found on
Acer Iconia Tab A500 (Android tablet device).

The Embedded Controller is ENE KB930 and it's running firmware customized
for the A500. The firmware interface may be reused by some other sibling
Acer tablets, although none of those tablets are supported in upstream yet.
Please review and apply, thanks in advance!

ATTENTION! This series depends on a-yet-unapplied patch from Lubomir Rintel
           which adds the device-tree binding for the ENE controller [1].

           It also depend on the pending patch that adds battery temperature
           properties to the battery binding [2].
