	oscillators and PLLs. Devices can use a common clock API to request
	a particular clock rate and check on available clocks. Clocks can
	feed into other clocks in a tree structure, with multiplexers to
	choose the source for each clock.

	Much clock configuration in U-Boot is either set up by the FSP, or
	set up by U-Boot itself but only statically. Thus the driver does not
	support changing clock rates, only querying them.
