-Dialog Semiconductor DA9150 Charger Power Supply bindings
-
-Required properties:
-- compatible: "dlg,da9150-charger" for DA9150 Charger Power Supply
-
-Optional properties:
-- io-channels: List of phandle and IIO specifier pairs
-- io-channel-names: List of channel names used by charger
-      ["CHAN_IBUS", "CHAN_VBUS", "CHAN_TJUNC", "CHAN_VBAT"]
-  (See Documentation/devicetree/bindings/iio/iio-bindings.txt for further info)

-Example:
-
-	da9150-charger {
-		compatible = "dlg,da9150-charger";
-
-		io-channels = <&gpadc 0>,
-			      <&gpadc 2>,

-Dialog Semiconductor DA9150 Fuel-Gauge Power Supply bindings
-
-Required properties:
-- compatible: "dlg,da9150-fuel-gauge" for DA9150 Fuel-Gauge Power Supply
-
-Optional properties:
-- dlg,update-interval: Interval time (milliseconds) between battery level checks.
-- dlg,warn-soc-level: Battery discharge level (%) where warning event raised.
-      [1 - 100]
-- dlg,crit-soc-level: Battery discharge level (%) where critical event raised.
-  This value should be lower than the warning level.
-      [1 - 100]
-
-
-Example:
-
-	fuel-gauge {
-		compatible = "dlg,da9150-fuel-gauge";
-
-		dlg,update-interval = <10000>;
-		dlg,warn-soc-level = /bits/ 8 <15>;
-		dlg,crit-soc-level = /bits/ 8 <5>;
-	};
