[PATCH v4 0/3] ARM: dts: add Kobo Clara 2E

[Andreas Kemnade]

Add a basic device tree for the Kobo Clara 2E Ebook reader.
It is equipped with an i.MX6SLL SoC. EPDC PMIC drivers
are not ready for mainline yet.

Changes in V4:
- fix order of pinmux nodes
- remove some blank lines

Changes in V3:
- removed 30MegaOhm current sense resistor nonsense

Changes in V2:
- improved commit message about devices without binding

[PATCH v4 1/3] dt-bindings: arm: fsl: add compatible strings for Kobo Clara 2E

[Andreas Kemnade]

Adds compatible strings for the Kobo Clara 2E eBook reader.
There are two variants differing in the EPD PMIC used.

[PATCH v4 2/3] ARM: dts: imx: Add devicetree for Kobo Clara 2E

[Andreas Kemnade]

Adds a devicetree for the Kobo Clara 2E Ebook reader. It is based
on boards marked with "37NB-E60K2M+4A2" or "37NB-E60K2M+4B0". It is
equipped with an i.MX6SLL SoC.

Expected to work:
  - Buttons
  - Wifi
  - Bluetooth
    (if Wifi is initialized first, driver does not handle regulators
     yet)
  - LED
  - uSD
  - USB
  - RTC
  - Touchscreen

Add human-readable comments for devices without mainlined driver and
binding. Such comments can e.g. be help to find testers if someone
starts to work on the missing drivers.

My bot found new DTB warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade
