158 synthesizer. Each chip has different number of PLLs and outputs.
159 For example, the CDCE925 contains two PLLs with spread-spectrum
160 clocking support and five output dividers. The driver only supports
161 the following setup, and uses a fixed setting for the output muxes.
162 Y1 is derived from the input clock
163 Y2 and Y3 derive from PLL1
164 Y4 and Y5 derive from PLL2
165 Given a target output frequency, the driver will set the PLL and
