Configure Motion Sensors

EC sensors are used for the following capabilities:

• Accelerometers in base and lid measure lid angle to toggle between laptop and tablet modes.
• Ambient light sensors control display backlight level.
• All sensor types, including gyroscope, e-compass, and pressure, are used by Android apps.
• Special sync sensor type, synchronizes sensor events with AP.

TODO - there is good content available in the most recent Chrome EC overview presentation that can be added here.
