[PATCH 1/2 v2] dt-bindings: power: Extend battery bindings with type

[PATCH 1/2 v2] dt-bindings: power: Extend battery bindings with type

[Linus Walleij]

This adds a battery-type property and bindings for the different
"technologies" that are used in Linux. More types can be added.

This is needed to convert the custom ST-Ericsson AB8500 battery
properties over to the generic battery bindings.

Cc: devicetree@vger.kernel.org
Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
---
ChangeLog v1->v2:
- Add devicetree list to Cc
- Use "device-chemistry" instead of "battery-type" as this
  has precedence in standards.
I need a bunch of new bindings for switch the STE AB8500 custom
bindings out, but I need to start somewhere, this is as good as
any place to start.

Waiting a bit to give Rob a chance to review this. From my side
it looks good.

Thanks Rob, Sebastian tell me if you can fix this when applying
or if you want me to respin the patch.

No, that's fine. I queued both patches with type changed to
chemistry in the commit messages.
