  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.

 115           The chip contains two PLLs with spread-spectrum clocking support and
 116           five output dividers. The driver only supports the following setup,
 117           and uses a fixed setting for the output muxes.
 118           Y1 is derived from the input clock
 119           Y2 and Y3 derive from PLL1
 120           Y4 and Y5 derive from PLL2
