Both adp8860 and adp8870 define some extensions to the
backlight class. This causes warnings:
Warning: /sys/class/backlight/<backlight>/ambient_light_level is defined 2 times: /sys/class/backlight/<backlight>/ambient_light_level:8 /sys/class/backlight/<backlight>/ambient_light_level:30
Warning: /sys/class/backlight/<backlight>/ambient_light_zone is defined 2 times: /sys/class/backlight/<backlight>/ambient_light_zone:18 /sys/class/backlight/<backlight>/ambient_light_zone:40
As ABI definitions shouldn't be duplicated.
Unfortunately, the ABI is dependent on the specific device
features. As such, ambient_light_level range is somewhat
different among the supported devices.
The ambient_light_zone is even worse: the meanings of each
preset are different, and there's no ABI to retrieve
the supported types nor their meanins. Unfortunately,
it is too late to fix it without causing regressions,
as this has been used since Kernel v2.6.35.
Rewrite those ABI documentation using the current documentation
as a reference, and double-checking at the datasheets:
https://www.analog.com/media/en/technical-documentation/data-sheets/ADP8870.pdfhttps://www.analog.com/media/en/technical-documentation/data-sheets/ADP8860.pdf
in order to properly document the differences between those two
drivers.

This patch simply adds a newline character at end-of-file to those
files in Documentation/ that currently lack one.
This is done for a few different reasons:
A) It's rather annoying when you do "cat some_file.txt" that your
prompt/cursor ends up at the end of the last line of output rather
than on a new line.
B) Some tools that process files line-by-line may get confused by the
lack of a newline on the last line.
C) The "\ No newline at end of file" line in diffs annoys me for some
reason.
So, let's just add the missing newline once and for all.
