  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
