Subject: [PATCH 0/2] Add driver for keyboard backlight on Magic keyboards
 found on T2 Macs

This patchseries adds support for the internal keyboard backlight of
Macs with Apple's "Magic" keyboard (MacBookPro16,* and MacBookAir9,1),
and also documents what names should be used for keyboard backlight
leds in Documentation/leds/well-known-leds.txt.

A separate driver for the purpose of backlight has been chosen because:

1. On the MacBookAir9,1 there is a USB device dedicated just for keyboard
  backlight by the name of Touchbar Backlight. Adding its support to any other
  hid-driver breaks the device.

2. Its now possible to use drm on the Touch Bar (similar to what macOS does).
  So, the Touch Bar drivers intended to be upstreamed before are no longer used.
  https://lore.kernel.org/all/868AA58D-2399-4E4A-A6C6-73F88DB13992@live.com/
  The driver that supports drm is still out of tree and yet to be submitted.
