[PATCH v3 0/6] power: supply: Lenovo Yoga C630 EC

[Dmitry Baryshkov]

This adds binding, driver and the DT support for the Lenovo Yoga C630
Embedded Controller, to provide battery information.

Support for this EC was implemented by Bjorn, who later could not work
on this driver. I've picked this patchset up and updated it following
the pending review comments.

DisplayPort support is still not a part of this patchset. It uses EC
messages to provide AltMode information rather than implementing
corresponding UCSI commands. However to have a cleaner uAPI story, the
AltMode should be handled via the same Type-C port.

Merge strategy: the driver bits depend on the platform/arm64 patch,
which adds interface for the subdrivers. I'd either ask to get that
patch merged to the immutable branch, which then can be picked up by
power/supply and USB trees or, to make life simpler, ack merging all
driver bits e.g. through USB subsystem (I'm biased here since I plan to
send more cleanups for the UCSI subsystem, which would otherwise result
in cross-subsystem conflicts).

Changes in v3:
- Split the driver into core and power supply drivers,
- Added UCSI driver part, handling USB connections,
- Fixed Bjorn's address in DT bindings (Brian Masney)
- Changed power-role for both ports to be "dual" per UCSI
- Link to v2: https://lore.kernel.org/linux-arm-msm/20230205152809.2233436-1-dmitry.baryshkov@xxxxxxxxxx/

Changes in v2:
- Dropped DP support for now, as the bindings are in process of being
  discussed separately,
- Merged dt patch into the same patchseries,
- Removed the fixed serial number battery property,
- Fixed indentation of dt bindings example,
- Added property: reg and unevaluatedProperties to the connector
  bindings.
