  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.

 112           This driver supports the TI CDCE913/925/937/949 programmable clock
 113           synthesizer. Each chip has different number of PLLs and outputs.
 114           For example, the CDCE925 contains two PLLs with spread-spectrum
 115           clocking support and five output dividers. The driver only supports
 116           the following setup, and uses a fixed setting for the output muxes.
 117           Y1 is derived from the input clock
 118           Y2 and Y3 derive from PLL1
 119           Y4 and Y5 derive from PLL2
