+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,rtc-qpnp".
+ - reg: Specify the peripheral id for device. Currently there
+ are two sub-peripherals - rtc base and alarm base.
+ - 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@60 {
+ compatible = "qcom,rtc-qpnp";
+ reg = <0x60>, <0x61>;
+ interrupts = <0x0 0x61 0x1 IRQ_TYPE_EDGE_RISING>;
+ };
