Subject: [PATCH v2 0/3] Support wakeup methods of Atmel maXTouch controllers
Some Atmel maXTouch controllers, like mXT1386 and mXT3432S1 for example,
have a WAKE line that needs to be asserted in order to wake controller
from a deep sleep, otherwise it will be unusable. This series implements
support for the wakeup methods in accordance to the mXT1386 datasheet [1],
see page 29 (chapter "5.8 WAKE Line").
The mXT1386 is a widely used controller found on many older Android tablet
devices. Touchscreen on Acer A500 tablet now works properly after this
series.
This patchset is a continuation of the work originally started by
Jiada Wang [2].
