+	  Say N to disable Embedded Controller /sys/kernel/debug interface
+
+	  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.
