Subject: [PATCH v3 1/2] dt-bindings: power: Convert ingenic,battery.txt to YAML
Convert the textual documentation of Device Tree bindings for the
Ingenic JZ47xx SoCs battery to YAML.
Signed-off-by: Artur Rojek <contact@...ur-rojek.eu>

Changes:
v2: move introduction of new compatibles into a separate patch
v3: - drop description of `io-channels` property and set its maxItems,
- remove redundant quotes in `io-channel-names` property,
- drop `items` for `monitored-battery` property

-* Ingenic JZ47xx battery bindings
-
-Required properties:
-
-- compatible: Must be "ingenic,jz4740-battery".
-- io-channels: phandle and IIO specifier pair to the IIO device.
- Format described in iio-bindings.txt.
-- monitored-battery: phandle to a "simple-battery" compatible node.
-
-The "monitored-battery" property must be a phandle to a node using the format
-described in battery.txt, with the following properties being required:
-
-- voltage-min-design-microvolt: Drained battery voltage.
-- voltage-max-design-microvolt: Fully charged battery voltage.
-
-Example:
-
-#include <dt-bindings/iio/adc/ingenic,adc.h>
-
-simple_battery: battery {
- compatible = "simple-battery";
- voltage-min-design-microvolt = <3600000>;
- voltage-max-design-microvolt = <4200000>;
