+Palmas RTC controller bindings
+
+Required properties:
+- compatible:
+  - "ti,palmas-rtc" for palma series of the RTC controller
+- interrupts: Interrupt number of RTC submodule on device.
+
+Optional properties:
+
+- ti,backup-battery-chargeable: The Palmas series device like TPS65913 or
+	TPS80036 supports the backup battery for powering the RTC when main
+	battery is removed or in very low power state. The backup battery
+	can be chargeable or non-chargeable. This flag will tells whether
+	battery is chargeable or not. If charging battery then driver can
+	enable the charging.
+- ti,backup-battery-charge-high-current: Enable high current charging in
+	backup battery. Device supports the < 100uA and > 100uA charging.
+	The high current will be > 100uA. Absence of this property will
+	charge battery to lower current i.e. < 100uA.
+
+Example:
+	palmas: tps65913@58 {
+		...
+		palmas_rtc: rtc {
+			compatible = "ti,palmas-rtc";
+			interrupt-parent = <&palmas>;
+			interrupts = <8 0>;
+			ti,backup-battery-chargeable;
+			ti,backup-battery-charge-high-current;
+		};
+		...
+	};
