 TI Real Time Clock
 
 Required properties:
-- compatible: "ti,da830-rtc"
+- compatible:
+	- "ti,da830-rtc"  - for RTC IP used similar to that on DA8xx SoC family.
+	- "ti,am3352-rtc" - for RTC IP used similar to that on AM335x SoC family.
+			    This RTC IP has special WAKE-EN Register to enable
+			    Wakeup generation for event Alarm. It can also be
+			    used to control an external PMIC via the
+			    pmic_power_en pin.
+	- "ti,am4372-rtc" - for RTC IP used similar to that on AM437X SoC family.
 - reg: Address range of rtc register set
 - interrupts: rtc timer, alarm interrupts in order
 - interrupt-parent: phandle for the interrupt controller
 
+Optional properties:
+- system-power-controller: whether the rtc is controlling the system power
+  through pmic_power_en
+- clocks: Any internal or external clocks feeding in to rtc
+- clock-names: Corresponding names of the clocks
+
