Subject: [PATCH 1/2] dt-bindings: remoteproc: Add SM8750 MPSS and CDSP
Add remote processor PAS loaders for SM8750 MPSS (modem) and CDSP
processors. Both are compatible with earlier SM8650 with minor
differences:
1. SM8750 CDSP has one more sixth shutdown interrupt.
2. SM8750 MPSS lacks fifth memory region for Qlink Logging, according to
downstream sources. There might be other differences, because the
modem currently crashes after starting.
Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@...aro.org>

DTS for both of these will follow up after merge window. Work in
progress is available at:
