Subject[RFC PATCH 00/10] Netronix embedded controller driver for Kobo and Tolino ebook readers
Date
Hi,

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 the vendor kernel sources, but in order to
all information in a single place, I documented the register interface
of the EC on GitHub[4].

A few things still needs to be ironed out, hence the RFC tag:
- The reboot/reset handler in patch 3/10 calls into I2C code, which may
sleep, but reboot handlers are apparently not allowed to sleep.
- I'm not sure I got the YAML DT bindings right. I have also included
the plain text DT bindings for reference.
