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.

Gwendal Grignou (4):
  iio: cros_ec: Add sign vector in core for backward compatibility
  iio: cros_ec_accel_legacy: Fix incorrect channel setting
  iio: cros_ec_accel_legacy: Use cros_ec_sensors_core
  iio: cros_ec_accel_legacy: Add support for veyron-minnie

Changes in v4:
- In "Use cros_ec_sensors_core", fix return without unlock on the error
  path.
- Add acked for the last 2 patches.

Changes in v4:
- No change in iio/common/cros_ec_sensors
- Split cros_ec_accel_legacy code in 3:
  - fix an error in channel setting.
  - remove duplicate code in cros_ec_accel, use cros_ec_sensors_core.
  - extend cros_ec_accel to ARM device.
- Define cros_ec_accel_legacy_read_cmd() as static.

Changes in v3:
- Fix commit message, add reviewed-by for first patch.

Changes in v2:
- Readd empty line to reduce amount of change in patch.
- Remove Keywords used by ChromeOS commit queue.
