+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.

IIRC, ti,hwmods has been removed on omap4.

Sure, I will remove it from the example.

Just one example is enough.

Okay.
