+          An Embedded Controller typically is available on laptops and reads
+          sensor values like battery state and temperature.
+          The kernel access the EC through ACPI parsed code provided by BIOS
+          tables.
+          Thus this option is a debug option that helps to write ACPI drivers
+          and can be used to identify ACPI code or EC firmware bugs.
