In linux kernel since version 3.10 (release Date: 2013-06-30)
This driver supports the TI CDCE913/925/937/949 programmable clock
synthesizer. Each chip has different number of PLLs and outputs.
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.
