160 This driver supports the TI CDCE913/925/937/949 programmable clock
161 synthesizer. Each chip has different number of PLLs and outputs.
162 For example, the CDCE925 contains two PLLs with spread-spectrum
163 clocking support and five output dividers. The driver only supports
164 the following setup, and uses a fixed setting for the output muxes.
165 Y1 is derived from the input clock
166 Y2 and Y3 derive from PLL1
167 Y4 and Y5 derive from PLL2
168 Given a target output frequency, the driver will set the PLL and
169 divider to best approximate the desired output.
