docs: ABI: sysfs-class-led-trigger-pattern: remove hw_pattern duplication

2020-10-30T12:15:03+00:00

The ABI files are supposed to be unique. Yet,
in the specific case of hw_pattern, there are some duplicated
entries as warned by scripts/get_abi.pl:

	Warning: /sys/class/leds//hw_pattern is defined 3 times:  Documentation/ABI/testing/sysfs-class-led-trigger-pattern:14  Documentation/ABI/testing/sysfs-class-led-driver-sc27xx:0  Documentation/ABI/testing/sysfs-class-led-driver-el15203000:0

Drop the duplication from the ABI files, moving the specific
definitions to files inside Documentation/leds.

leds: we don't want people to use LED subsystem for vibrations

2020-08-17T16:04:15+00:00

Remove notes about vibrations, as that is better done using input
subsystem.

Merge tag 'leds-5.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/pavel/linux-leds

2020-08-06T02:24:27+00:00

Pull LED updates from Pavel Machek:
 "Okay, so... this one is interesting. RGB LEDs are very common, and we
  need to have some kind of support for them. Multicolor is for
  arbitrary set of LEDs in one package, RGB is for LEDs that can produce
  full range of colors. We do not have real multicolor LED that is not
  RGB in the pipeline, so that one is disabled for now.

  You can expect this saga to continue with next pull requests"

leds: multicolor: Introduce a multicolor class definition

2020-07-22T12:41:29+00:00

Introduce a multicolor class that groups colored LEDs
within a LED node.

The multicolor class groups monochrome LEDs and allows controlling two
aspects of the final combined color: hue and lightness. The former is
controlled via the intensity file and the latter is controlled
via brightness file.

leds: core: Add support for composing LED class device names

2019-07-25T18:07:52+00:00

Add generic support for composing LED class device name. The newly
introduced led_compose_name() function composes device name according
to either  or  pattern,
depending on the configuration of initialization data.

Backward compatibility with in-driver hard-coded LED class device
names is assured thanks to the default_label and devicename properties
of newly introduced struct led_init_data.

In case none of the aforementioned properties was found, then, for OF
nodes, the node name is adopted for LED class device name.

At the occassion of amending the Documentation/leds/leds-class.txt
unify spelling: colour -> color.

Alongside these changes added is a new tool - tools/leds/get_led_device_info.sh.
The tool allows retrieving details of a LED class device's parent device,
which proves that using vendor or product name for devicename part
of LED name doesn't convey any added value since that information had been
already available in sysfs. The script performs also basic validation
of a LED class device name.

docs: leds: add it to the driver-api book

2019-07-15T12:20:28+00:00

The contents of leds driver docs is messy: it has lots of
admin-guide stuff and kernel internal ones, just like other
driver subsystems.

I'm opting to keep the dir at the same place and just add
a link to it. This makes clearer that this require changes.

docs: leds: convert to ReST

2019-06-28T18:57:31+00:00

Rename the leds documentation files to ReST, add an
index for them and adjust in order to produce a nice html
output via the Sphinx build system.

At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.

Documentation: Use "while" instead of "whilst"

2018-11-20T16:30:43+00:00

Whilst making an unrelated change to some Documentation, Linus sayeth:

  | Afaik, even in Britain, "whilst" is unusual and considered more
  | formal, and "while" is the common word.
  |
  | [...]
  |
  | Can we just admit that we work with computers, and we don't need to
  | use þe eald Englisc spelling of words that most of the world never
  | uses?

dictionary.com refers to the word as "Chiefly British", which is
probably an undesirable attribute for technical documentation.

Replace all occurrences under Documentation/ with "while".
