+* Real-Time Clock for Qualcomm 8058/8921 PMICs
+
+Required properties:
+- compatible: should be one of the following.
+    * "qcom,pm8058-rtc"
+    * "qcom,pm8921-rtc"
+- reg: base address of the register region
+- reg-names: corresponding reg names for the regions listed in the 'reg'
+             property, must contain:
+     "rtc_base" - base of the RTC register region
+- interrupts: interrupt list for the RTC, must contain a single interrupt
+              specifier for the alarm interrupt
+- interrupt-names: corresponding interrupt names for the interrupts listed in
+                   the 'interrupts' property, must contain:
+     "alarm" - summary interrupt for PMIC peripherals
+
+Option properties:
+- linux,allow-set-time: indicates that the setting of RTC time is allowed by
+                        the host CPU
+
+Example:
+
+	rtc {
+		compatible = "qcom,pm8921-rtc";
+		reg = <0x11D>;
+		reg-names = "rtc_base";
+		interrupts = <0x27 0>;
+		interrupt-names = "alarm";
+	};
