+Description:    Display fw status registers content
+
+                The ME FW writes its status information into fw status
+                registers for BIOS and OS to monitor fw health.
+
+                The register contains running state, power management
+                state, error codes, and others. The way the registers
+                are decoded depends on PCH or SoC generation.
+                Also number of registers varies between 1 and 6
+                depending on generation.

-Description:
-                This file allows to control the input triggers that
-                turn on the keyboard backlight illumination that is
-                disabled because of inactivity.
-                Read the file to see the triggers available. The ones
-                enabled are preceded by '+', those disabled by '-'.
-
-                To enable a trigger, write its name preceded by '+' to
-                this file. To disable a trigger, write its name preceded
-                by '-' instead.
-
-                For example, to enable the keyboard as trigger run:
-                    echo +keyboard > /sys/class/leds/dell::kbd_backlight/start_triggers
-                To disable it:
-                    echo -keyboard > /sys/class/leds/dell::kbd_backlight/start_triggers
-
-                Note that not all the available triggers can be configured.

-Contact:        Gabriele Mazzotta <gabriele.mzt@gmail.com>,
-                Pali Rohár <pali.rohar@gmail.com>
-Description:
-                This file allows to specify the interval after which the
-                keyboard illumination is disabled because of inactivity.
-                The timeouts are expressed in seconds, minutes, hours and
-                days, for which the symbols are 's', 'm', 'h' and 'd'
-                respectively.
-
-                To configure the timeout, write to this file a value along
-                with any the above units. If no unit is specified, the value
-                is assumed to be expressed in seconds.
-
-                For example, to set the timeout to 10 minutes run:
-                    echo 10m > /sys/class/leds/dell::kbd_backlight/stop_timeout
-
-                Note that when this file is read, the returned value might be
-                expressed in a different unit than the one used when the timeout
-                was set.
-
-                Also note that only some timeouts are supported and that
-                some systems might fall back to a specific timeout in case
-                an invalid timeout is written to this file.
