Subject: [PATCH 0/2] platform/surface: aggregator_tabletsw: Add support for book mode

Surface devices with a type-cover have an additional "book" mode. This
mode is activated when the device is oriented in portrait mode and the
type-cover is in an open position (including completely folded back;
unlike in landscape orientation there are no special modes for any of
the intermediate positions).

Currently, this mode is unsupported by the tablet switch driver, leading
to an error message (see individual commits for the exact messages).
Since the keyboard and touchpad input gets deactivated in this mode, map
it to tablet-mode.

I've split this change into two patches, one for each of the subsystems
(KIP and POS). This a) allows proper attribution via the "Fixes" tag and
b) with that should allow them to be backported fairly easily.

    KIP subsystem
  platform/surface: aggregator_tabletsw: Add support for book mode in
    POS subsystem
