Message

veyron_minnie - ASUS Chromebook Flip C100PA - embedded controller
controls two accelerometers, one in the lid, one in the base.
However, the EC firmware does not follow the new interface that
cros_ec_accel driver use.
Extend the legacy driver used on glimmer - Lenovo ThinkPad 11e
Chromebook - to veyron_minnie.
veyron_minnie being ARM based, issue command over the I2C bus to the EC
instead of relying on the shared registers over LPC.

  iio: cros_ec : Extend legacy support to ARM device
