+Subject: [PATCH 09/12] OMAP3+: SR: make notify independent of class
+
+Interrupt notification mechanism of SmartReflex can be used by the
+choice of implementation of the class driver. For example, Class 2 and
+Class 1.5 of SmartReflex can both use the interrupt notification to
+identify the transition of voltage or other events.
+
+Hence, the actual class does not matter for notifier. Let the class
+driver's handling decide how it should be used. SmartReflex driver
+should provide just the primitives.
