	  The common clock framework is a single definition of struct
	  clk, useful across many platforms, as well as an
	  implementation of the clock API in include/linux/clk.h.
	  Architectures utilizing the common struct clk should select
	  this option.

	help
	---help---
	  This driver supports the TI CDCE925 programmable clock synthesizer.
	  The chip contains two PLLs with spread-spectrum clocking support and
	  five output dividers. The driver only supports the following setup,
	  and uses a fixed setting for the output muxes.
	  Y1 is derived from the input clock
	  Y2 and Y3 derive from PLL1
	  Y4 and Y5 derive from PLL2
	  Given a target output frequency, the driver will set the PLL and
	  divider to best approximate the desired output.
