    Document device tree bindings for TI AM654/J721E SoC The Common Platform
    Time Sync (CPTS) module. The CPTS module is used to facilitate host control
    of time sync operations. Main features of CPTS module are:
      - selection of multiple external clock sources
      - 64-bit timestamp mode in ns with ppm and nudge adjustment.
      - control of time sync events via interrupt or polling
      - hardware timestamp of ext. events (HWx_TS_PUSH)
      - periodic generator function outputs (TS_GENFx)
      - PPS in combination with timesync router
      - Depending on integration it enables compliance with the IEEE 1588-2008
    standard for a precision clock synchronization protocol, Ethernet Enhanced
    Scheduled Traffic Operations (CPTS_ESTFn) and PCIe Subsystem Precision Time
    Measurement (PTM).
