From: Linus Walleij <hidden>

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. Signed-off-by: Linus Walleij <redacted> --- 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. --- .../devicetree/bindings/power/supply/battery.yaml | 14 ++++++++++++++ 1 file changed, 14 insertions(+)
