   13   The TI K3 family of SoCs usually have one or more TI DSP Core sub-systems
   14   that are used to offload some of the processor-intensive tasks or algorithms,
   15   for achieving various system level goals.
   16 
   17   These processor sub-systems usually contain additional sub-modules like
   18   L1 and/or L2 caches/SRAMs, an Interrupt Controller, an external memory
   19   controller, a dedicated local power/sleep controller etc. The DSP processor
   20   cores in the K3 SoCs are usually either a TMS320C66x CorePac processor or a
   21   TMS320C71x CorePac processor.
   22 
   23   Each DSP Core sub-system is represented as a single DT node. Each node has a
   24   number of required or optional properties that enable the OS running on the
   25   host processor (Arm CorePac) to perform the device management of the remote
   26   processor and to communicate with the remote processor.
