+description:
+  Texas Instruments SmartReflex is an on-chip adaptive power management
+  technology integrated into TI's OMAP and other SoCs. It dynamically
+  adjusts voltage and frequency for different chip domains in real time
+  to compensate for process, voltage, and temperature (PVT) variations.
+  Dedicated hardware sensors and control logic continuously monitor
+  conditions and apply the lowest safe voltage for the required performance
+  level.

-Texas Instruments SmartReflex binding
-
-SmartReflex is used to set and adjust the SoC operating points.
-
-
-Required properties:
-
-compatible: Shall be one of the following:
-	    "ti,omap3-smartreflex-core"
-	    "ti,omap3-smartreflex-mpu-iva"
-	    "ti,omap4-smartreflex-core"
-	    "ti,omap4-smartreflex-mpu"
-	    "ti,omap4-smartreflex-iva"
-
-reg: Shall contain the device instance IO range
-
-interrupts: Shall contain the device instance interrupt
-
-
-Optional properties:
-
-ti,hwmods: Shall contain the TI interconnect module name if needed
-	   by the SoC
-
-
-Example:
-
-	smartreflex_iva: smartreflex@4a0db000 {
-		compatible = "ti,omap4-smartreflex-iva";
-		reg = <0x4a0db000 0x80>;
