  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.

 112           and uses a fixed setting for the output muxes.
 113           Y1 is derived from the input clock
 114           Y2 and Y3 derive from PLL1
 115           Y4 and Y5 derive from PLL2
