     13  A simple bus enabling access to shared peripherals.
     14
     15  The "spba-bus" follows the "simple-bus" set of properties, as
     16  specified in the Devicetree Specification.  It is an extension of
     17  "simple-bus" because the SDMA controller uses this compatible flag to
     18  determine which peripherals are available to it and the range over which
     19  the SDMA can access.  There are no special clocks for the bus, because
     20  the SDMA controller itself has its interrupt and clock assignments.
