The K3 J721S2 SoCs have three dual-core R5F subsystems, one in MCU voltage domain and the other two in MAIN voltage domain. These R5F clusters are similar to the R5F clusters in J7200 SoCs.
Compatible Info is updated to support J721S2 SoCs.

From: Hari Nagalla hnagalla@ti.com
The K3 J721S2 SoCs have two C71x DSP subsystems in MAIN voltage domain, and there are no C66x DSP subsystems on these SoCs. The C71x DSP subsystem is a slighly updated version of the C71x DSP subsystem on J721e. The C71x DSPs are 64 bit machine with fixed and floating point DSP operations.
Extend support to the C71x DSPs with J721S2 compatible strings.
