Mauro Carvalho Chehab 26a0755304 docs: ABI: sysfs-class-led-trigger-pattern: remove hw_pattern duplication
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/<led>/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.

What: /sys/class/leds/<led>/pattern
Date: September 2018
KernelVersion: 4.20
Description:
Specify a software pattern for the LED, that supports altering
the brightness for the specified duration with one software
timer. It can do gradual dimming and step change of brightness.
The pattern is given by a series of tuples, of brightness and
duration (ms).
The exact format is described in:
Documentation/devicetree/bindings/leds/leds-trigger-pattern.txt
What: /sys/class/leds/<led>/hw_pattern
Date: September 2018
KernelVersion: 4.20
Description:
Specify a hardware pattern for the LED, for LED hardware that
supports autonomously controlling brightness over time, according
to some preprogrammed hardware patterns. It deactivates any active
software pattern.
Since different LED hardware can have different semantics of
hardware patterns, each driver is expected to provide its own
description for the hardware patterns in their documentation
file at Documentation/leds/.
What: /sys/class/leds/<led>/repeat
Date: September 2018
KernelVersion: 4.20
Description:
Specify a pattern repeat number. -1 means repeat indefinitely,
other negative numbers and number 0 are invalid.
This file will always return the originally written repeat
number.
