The Lenovo ThinkPad Yoga 11e 360 degree hinges style 2-in-1s use 2
accelerometers, 1 in the display and 1 in the base.
Kernel work is under way to also export the second accelerometer in
the base as an iio-device; and userspace work is underway to use
both accelerometers on 360 degree hinges style 2-in-1s (with 2 accels)
to figure out the angle between the 2 halves.
So far most orientation-matrix quirks have not cared much about the
Z-axis being correct, but in these 2 accelerometer setups getting
the Z-axis correct is important too.
