This driver supports the TI CDCE913/925/937/949 programmable clock

For example, the CDCE925 contains two PLLs with spread-spectrum
|
clocking support and five output dividers. The driver only supports
|
the following setup, and uses a fixed setting for the output muxes.
|
Y1 is derived from the input clock
|
Y2 and Y3 derive from PLL1
|
Y4 and Y5 derive from PLL2
|
Given a target output frequency, the driver will set the PLL and
|
divider to best approximate the desired output.
