      A phandle to a syscon device (see ../mfd/syscon.txt) used to access

      With this property in place we will export one or two clocks

      Test mode can be used to force the controller to function.

  xlnx,int-clock-stable-broken:

    description:
      When present, the controller always reports that the internal clock
      is stable even when it is not.
