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