+ This driver adds support for platform-profiles on platforms that

+
+ Platform-profiles can be used to control the platform behaviour. For
+ example whether to operate in a lower power mode, in a higher

+
+ This driver provides the sysfs interface and is used as the registration
+ point for platform specific drivers.
+
+ Which profiles are supported is determined on a per-platform basis and
