 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 CDCE925 programmable clock synthesizer.
105           The chip contains two PLLs with spread-spectrum clocking support and
106           five output dividers. The driver only supports the following setup,
107           and uses a fixed setting for the output muxes.
108           Y1 is derived from the input clock
109           Y2 and Y3 derive from PLL1
110           Y4 and Y5 derive from PLL2
