+Qualcomm RTC QPNP
+
+The RTC device supports 32bit RTC module housed inside QPNP PMIC's.
+The driver utilizes SPMI interface to communicate with the RTC module.
+RTC device is divided into two sub-peripherals one which controls
+basic RTC and other for controlling alarm.
+
+Required properties :
+ - compatible:  Should be "qcom,qpnp-rtc".
+ - reg:         Specify the peripheral id for device. Currently there
+                are two sub-peripherals - rtc base and alarm base.
+ - reg-names:   Specify the reg property as strings. Should be "rtc"
+                and "alarm", defining the rtc and alarm bases.
+ - interrupts:  Specifies alarm interrupt, only for alarm sub-peripheral.
+                For more info about interrupt cells see
+                Documentation/devicetree/bindings/spmi/qcom,spmi-pmic-arb.txt
+
+Example:
+	rtc@6000 {
+		compatible = "qcom,qpnp-rtc";
+		reg = <0x6000 0x6100>;
+		reg-names = "rtc", "alarm";
+		interrupts = <0x0 0x61 0x1 IRQ_TYPE_EDGE_RISING>;
+	};
