+description: |
+  This is a Linux interface to an RTC managed by firmware, hence it's
+  virtual from a Linux perspective.  The interface is 1 register where
+  an alarm time (in seconds) is to be written.
+  The alarm register is a simple scratch register shared between the
+  application processors (AP) and the secure co-processor (SCP.)  When
+  the AP suspends, the SCP will use the value of this register to
+  program an always-on timer before going sleep. When the timer expires,
+  the SCP will wake up and will then wake the AP.

-* Amlogic Virtual RTC (VRTC)
-
-This is a Linux interface to an RTC managed by firmware, hence it's
-virtual from a Linux perspective.  The interface is 1 register where
-an alarm time (in seconds) is to be written.
-
-Required properties:
-- compatible: should be "amlogic,meson-vrtc"
-- reg: physical address for the alarm register
-
-The alarm register is a simple scratch register shared between the
-application processors (AP) and the secure co-processor (SCP.)  When
-the AP suspends, the SCP will use the value of this register to
-program an always-on timer before going sleep. When the timer expires,
-the SCP will wake up and will then wake the AP.
-
-Example:
-
-	vrtc: rtc@0a8 {
-		compatible = "amlogic,meson-vrtc";
-		reg = <0x0 0x000a8 0x0 0x4>;
-	};
