The functionality of these DSP subsystems is similar to the C71x DSP subsystems on earlier k3 device J721S2. Each subsystem has a 48 KB of L1D configurable SRAM/Cache and 512 KB of L2 SRAM/Cache. This subsystem has a CMMU but is not currently used. The inter-processor communication between the main A72 cores and the C71x DSPs is achieved through shared memory and mailboxes. Add the DT nodes for these DSP processor sub-systems.
