[PATCH v2 00/10] Netronix embedded controller driver for Kobo and Tolino ebook readers

This patchset adds basic support for the embedded controller found on
older ebook reader boards designed by/with the ODM Netronix Inc.[1] and
sold by Kobo or Tolino, for example the Kobo Aura and the Tolino Shine.
These drivers are based on information contained in the vendor kernel
sources, but in order to all information in a single place, I documented
the register interface of the EC on GitHub[2].

As previously, I'm not sure I got the YAML DT bindings right. I have
included the plain text DT bindings for reference, in the patch
descriptions where they are relevant.

Changes in v2:
- Moved txt DT bindings to patch descriptions and removed patch 1/10
"DT bindings in plain text format"
- New patch 7/10 "rtc: Introduce RTC_TIMESTAMP_END_2255"
- Rebased on 5.9-rc3
- Various other changes which are documented in each patch

v1:
