  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.

 104           This driver supports the TI CDCE913/925/937/949 programmable clock
 105           synthesizer. Each chip has different number of PLLs and outputs.
 106           For example, the CDCE925 contains two PLLs with spread-spectrum
 107           clocking support and five output dividers. The driver only supports
 108           the following setup, and uses a fixed setting for the output muxes.
 109           Y1 is derived from the input clock
 110           Y2 and Y3 derive from PLL1
 111           Y4 and Y5 derive from PLL2
 112           Given a target output frequency, the driver will set the PLL and
 113           divider to best approximate the desired output.
