+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.

-KernelVersion: 3.19
-Contact: Gabriele Mazzotta <gabriele.mzt@gmail.com>,
- Pali Rohár <pali.rohar@gmail.com>
-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.

-What: /sys/class/leds/dell::kbd_backlight/stop_timeout
-Date: December 2014
-KernelVersion: 3.19
-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.
