Commit Message

Andreas Kemnade June 4, 2022, 1:53 p.m. UTC
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)

Signed-off-by: Andreas Kemnade <andreas@kemnade.info>

Changes in V2:
- no underscores in node names
- fix key/led node names
- correct names for pinctl grps

Hi Andreas,

a few minor nits I saw..

I know that the DT is sorted alphabetical, except for the iomuxc node.
Very often this node is the last one to increase the readability of the
DT.

Do we not have dedicated devices for those GPIOs, so you don't need the
hog group.

Regards,
  Marco
