    clk: Add Si5341/Si5340 driver · 3044a860
    Mike Looijmans authored
    Adds a driver for the Si5341 and Si5340 chips. The driver does not fully
    support all features of these chips, but allows the chip to be used
    without any support from the "clockbuilder pro" software.
    
    If the chip is preprogrammed, that is, you bought one with some defaults
    burned in, or you programmed the NVM in some way, the driver will just
    take over the current settings and only change them on demand. Otherwise
    the input must be a fixed XTAL in its most basic configuration (no
    predividers, no feedback, etc.).
    
    The driver supports dynamic changes of multisynth, output dividers and
    enabling or powering down outputs and multisynths.
