Subject: [PATCH 0/4] power: supply: add battery driver for netronix ec

This series adds a new battery driver for the netronix embedded
controller multi-function device.

Bindings are updated supporting a monitored battery, and battery
description is added to kobo aura device-tree.

Changes in v2:
- Fixed identity mixup between from address and SoB.
  (Reported-by: Krzysztof Kozlowski <krzk@...nel.org>)
- Changed patch ordering, device-tree first.
- Separated new driver and mfd subdevice changes into separate patches.
  (Reported-by: Jonathan Neuschäfer <j.neuschaefer@....net>)
- reworded Kconfig to explicitly mention device-tree
  instead of vague firmware tables expression.
