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].

[2]: https://github.com/neuschaefer/linux/wiki/Netronix-MSP430-embedded-controller

v9:
- Fixed a bug in the error handling of ntxec_probe,
  Reported-by: kernel test robot <lkp@intel.com>
- Added Thierry Reding's ACK to the PWM patch

v8:
- https://lore.kernel.org/lkml/20210116194826.3866540-1-j.neuschaefer@gmx.net/
- MFD: Add missing module metadata to the core driver
- PWM/RTC: Copy dev.of_node from the parent device, to ensure that these
  devices are linked to the devicetree node

v7:
- https://lore.kernel.org/lkml/20210109180220.121511-1-j.neuschaefer@gmx.net/
- Adjust the RTC patch to a change in the RTC API:
  rtc_register_device is now devm_rtc_register_device.
- Add a #define for the known firmware version (0xd726).
  Lee Jones suggested doing this in a follow-up patch, but since I'm
  respinning the series anyway, I'm doing it here.

what is the fate of this one, looks like it got all acks from
maintainers.

I'll apply it when -rc1 is out.
