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

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