This adds a sensor-specific attentuation factor, which will be applied to the ALS raw sensor readings on the EC. This is to account for the attenutation due to glass, tinting, etc. BUG=chrome-os-partner:34590 BRANCH=ToT,Samus TEST=manual In a root shell, run this: cd /sys/bus/acpi/drivers/acpi_als/ACPI0008:00/iio:device1 while true; do cat in_illuminance_raw; sleep 1 ;done Shine a flashlight on the ALS.
