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

 101           five output dividers. The driver only supports the following setup,
 102           and uses a fixed setting for the output muxes.
 103           Y1 is derived from the input clock
 104           Y2 and Y3 derive from PLL1
 105           Y4 and Y5 derive from PLL2
