This driver supports the TI CDCE925 programmable clock synthesizer.
The chip 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.

Even if not documented in the datasheet, the Armada 370 SoC can actually

Add an entry in the gating_desc table to be able to reference the CESA
gateclk in the crypto node.

Add initial clock support for Marvell PXA1928. The PXA1928 is a mobile
