* 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>;
};
ingenic_battery {
compatible = "ingenic,jz4740-battery";
io-channels = <&adc INGENIC_ADC_BATTERY>;
io-channel-names = "battery";
monitored-battery = <&simple_battery>;
};
