[v3,00/10] Summit SMB3xx driver & device-tree

We gathered existing patches, fixed and improved what we could and
final result is an working charging driver with device-tree support
for Nexus 7.

At this moment charging works with:
 - Nexus 7 2012 (grouper and tilapia)
 - Nexus 7 2013 (flo and deb)
 - ... and there are more devices equipped with these chargers.

Changelog:

v3: - The uint32 type now isn't specified for standard units in the SMB
      DT binding because standard units already have a type.
      Thanks to Rob Herring for the suggestion!

    - The battery binding changes are rebased on top of the new battery.yaml

    - The new battery temperature DT properties now have shorter names
      and use <min max> format. Thanks to Rob Herring for the suggestion!

    - Added new patch that adds SMB charger node to the new Nexus 7 2012
      device-tree which has been merged into v5.9 kernel.

v2: - Addressed v1 review comments from Rob Herring and Sebastian Reichel
      by moving out common battery properties from the charger node into the
      battery-cell node.

    - power_supply_register() of the SMB driver converted to resource-managed
      API variant.

    - Improved DT property names of the SMB binding by making them to follow
      the generic power-supply naming scheme (-microvolts at the end, etc).

Hi,

I queued patches 1-8 (so everything besides the DTS changes). I
would like to see some more cleanups and will send a separate
patchset for them in a jiffy. Please test them, since I do not
have the hardware.
