A complete dump is available at https://github.com/larsks/yoga-11e-acpi/.
It looks like there is a single ACPI device with two I2C devices; see
https://github.com/larsks/yoga-11e-acpi/blob/master/dsdt.dsl#L10396.

The orientation issue can be handled with the appropriate
ACCEL_MOUNT_MATRIX in the hwdb, assuming that you are relying on
iio-sensor-proxy to act as the moderator between the accelerometer readings
and your desktop environment. The necessary patch to systemd for this
merged yesterday (

).
