[PATCH 0/4] TI K3 R5F and C71x support on J721S2

Hi All,

The following series enhances the K3 R5F and DSP remoteproc drivers to
add support for the R5F clusters and C71x DSP on the newer TI K3 J721S2
SoC family. The J721S2 SoCs have 3 R5FSS clusters, one in MCU voltage
domain and the other two in MAIN voltage domain. There are also 2 C71x
DSP subsystems in MAIN voltage domain. The R5FSS is similar to the R5FSS
in J7200 SoCs, while the C71x DSPs are similar to the C71x DSP on J721e
SoCs.

See J721S2 Technical Reference Manual (SPRUJ28 – NOVEMBER 2021)
for further details: http://www.ti.com/lit/pdf/spruj28

Regards
Hari

The TI K3 J721S2 SoCs have three dual-core Arm R5F clusters/subsystems,
with 2 R5F cores each, one in MCU voltage domain and the other two in
MAIN voltage domain.

These clusters are similar to J7200 R5F clusters. Compatible info is
updated for intuitively matching to the new J721S2 SoCs.

The TI K3 J721S2 SoCs have two TMS320C71x DSP subsystems, and does not
have any TMS320C66x DSP subsystems. The C71x DSP subsystem in J721S2
SoCs is a similar to the C71x DSP on J721e with some minor core IP updates.

Compatible info is updated for intuitvely matching to the new J721S2
SoCs.

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.

For all 4 patches:

Reviewed-by: Mathieu Poirier <mathieu.poirier@linaro.org>

It was a holiday last week in the US so I'll give more time for Rob to review this (should
he want to) before publishing.

Thanks,
