This adds a devicetree for the Kobo Aura 2 Ebook reader. It is based
on boards marked with "37NB-E60QL0+4B1". It is equipped with an i.MX6SL
SoC.

Expected to work:
  - Buttons
  - Wifi (with external module)
  - LED
  - uSD
  - USB
  - RTC
  - Fuel Gauge
  - Backlight (if the required regulator is probed before the backlight,
    specifying a supply is not supported by backlightdriver)

Generic node names. You could add suffix if needed, so either key or
key-cover.

The same. You also need property for color.

Bindings require all nodes to finish with grp. Here and in other places.

hmm, the example in
Documentation/devicetree/bindings/input/gpio-keys.yaml

shows names like I did. I usually expect to trust binding documentation
to have something acceptable.
