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

 104           This driver supports the TI CDCE925 programmable clock synthesizer.
 105           The chip contains two PLLs with spread-spectrum clocking support and
 106           five output dividers. The driver only supports the following setup,
 107           and uses a fixed setting for the output muxes.
 108           Y1 is derived from the input clock
 109           Y2 and Y3 derive from PLL1
 110           Y4 and Y5 derive from PLL2
