What: /sys/class/leds/dell::kbd_backlight/als_setting

Description:
This file allows to control the automatic keyboard
illumination mode on some systems that have an ambient
light sensor. Write 1 to this file to enable the auto
mode, 0 to disable it.
What: /sys/class/leds/dell::kbd_backlight/start_triggers
Date: December 2014
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.

* QEMU Firmware Configuration bindings for ARM
QEMU's arm-softmmu and aarch64-softmmu emulation / virtualization targets
provide the following Firmware Configuration interface on the "virt" machine
type:
- A write-only, 16-bit wide selector (or control) register,
- a read-write, 64-bit wide data register.
QEMU exposes the control and data register to ARM guests as memory mapped
registers; their location is communicated to the guest's UEFI firmware in the
DTB that QEMU places at the bottom of the guest's DRAM.
The guest writes a selector value (a key) to the selector register, and then
can read the corresponding data (produced by QEMU) via the data register. If
the selected entry is writable, the guest can rewrite it through the data
register.
The selector register takes keys in big endian byte order.
The data register allows accesses with 8, 16, 32 and 64-bit width (only at
offset 0 of the register). Accesses larger than a byte are interpreted as
arrays, bundled together only for better performance. The bytes constituting
such a word, in increasing address order, correspond to the bytes that would
have been transferred by byte-wide accesses in chronological order.
The interface allows guest firmware to download various parameters and blobs
that affect how the firmware works and what tables it installs for the guest
OS. For example, boot order of devices, ACPI tables, SMBIOS tables, kernel and
initrd images for direct kernel booting, virtual machine UUID, SMP information,
virtual NUMA topology, and so on.
The authoritative registry of the valid selector values and their meanings is
the QEMU source code; the structure of the data blobs corresponding to the
individual key values is also defined in the QEMU source code.
The presence of the registers can be verified by selecting the "signature" blob
with key 0x0000, and reading four bytes from the data register. The returned
signature is "QEMU".
The outermost protocol (involving the write / read sequences of the control and
data registers) is expected to be versioned, and/or described by feature bits.
The interface revision / feature bitmap can be retrieved with key 0x0001. The
blob to be read from the data register has size 4, and it is to be interpreted
as a uint32_t value in little endian byte order. The current value
(corresponding to the above outer protocol) is zero.
The guest kernel is not expected to use these registers (although it is
certainly allowed to); the device tree bindings are documented here because
this is where device tree bindings reside in general.
Required properties:
- compatible: "qemu,fw-cfg-mmio".
- reg: the MMIO region used by the device.
* Bytes 0x0 to 0x7 cover the data register.
* Bytes 0x8 to 0x9 cover the selector register.
* Further registers may be appended to the region in case of future interface
revisions / feature bits.
Example:
/ {
#size-cells = <0x2>;
#address-cells = <0x2>;
fw-cfg@9020000 {
compatible = "qemu,fw-cfg-mmio";
reg = <0x0 0x9020000 0x0 0xa>;
};
};

Here the ports describe data interfaces, and the links between them are
the connecting data buses. A single port with multiple connections can
