After switching to new led_classdev_register_ext() the validity

bb4e9af034 leds: core: Add support for composing LED class device names
Add generic support for composing LED class device name. The newly
introduced led_compose_name() function composes device name according
to either <color:function> or <devicename:color:function> 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.

b2b998c0f9 leds: class: Improve LED and LED flash class registration API
Replace of_led_classdev_register() with led_classdev_register_ext(), which
accepts easily extendable struct led_init_data, instead of the fixed
struct device_node argument. The latter can be now passed in an fwnode
property of the struct led_init_data.

The modification is driven by the need for passing additional arguments
required for the forthcoming generic mechanism for composing LED names.
Currently the LED name is conveyed in the "name" char pointer property of
the struct led_classdev. This is redundant since LED class device name
is accessible throughout the whole LED class device life time via
associated struct device's kobj->name property.

The change will not break any existing clients since the patch alters
also existing led_classdev{_flash}_register() macro wrappers, that pass
NULL in place of init_data, which leads to using legacy name
initialization path basing on the struct led_classdev's "name" property.

Three existing users of devm_of_led_classdev_registers() are modified
to use devm_led_classdev_register(), which will not impact their
operation since they in fact didn't need to pass struct device_node on
registration from the beginning.

0344e6166b leds: apu: drop superseeded apu2/3 led support
This driver only supports gpio-attached LEDs on apu1/2/3 boards,
but neither gpio's themselves, nor other gpio-attached devices
(eg. front button).

For apu2+ a newer, more complete driver exists, based on a generic
driver for the AMD SOCs gpio-controller, supporting LEDs as well
other devices. Therefore these boards don't need legacy support
from this driver anymore.

Both drivers claim the same device, so only one driver may exist
in a system, putting distros in the position to decide between
either apu2+ keys or apu1 led support.

Therefore drop the apu2+ led support from the old driver, solve
the conflict and reduce unnecessary code.

Introduce the LM36274 LED driver.  This driver uses the ti-lmu
MFD driver to probe this LED driver.  The driver configures only the
LED registers and enables the outputs according to the config file.

The driver utilizes the TI LMU (Lighting Management Unit) LED common
framework to set the brightness bits.

8c0f693c6e leds: avoid flush_work in atomic context
It turns out that various triggers use led_blink_setup() from atomic
context, so we can't do a flush_work there. Flush is still needed for
slow LEDs, but we can move it to sysfs code where it is safe.
