  • Add support for the Si5342, Si5344 and Si5345 chips. These are equivalent
    to the Si5341 family, but with more clock input options (which are not
    supported yet by this driver).

  • The Si5341 and Si5340 have multiple input clock options. So far, the driver
    only supported the XTAL input, this adds support for the three external
    clock inputs as well.

    If the clock chip isn't programmed at boot, the driver will default to the
    XTAL input as before. If there is no "xtal" clock input available, it will
    pick the first connected input (e.g. "in0") as the input clock for the PLL.
    One can use clock-assigned-parents to select a particular clock as input.

  • The variable n_den is initialized however that value is never read
    as n_den is re-assigned a little later in the two paths of a
    following if-statement. Remove the redundant assignment.

  • 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.
