Generic clocks are configurable clocks which run outside the system clock domain. They are often connected to peripherals which have an asynchronous component running independently of the bus clock, e.g. USB controllers, low-power timers and RTCs, etc.
Note that not all platforms have support for generic clocks; on such platforms, this API will not be available.
