[PATCH v5 0/5] arm64: dts: qcom: sdm630/660 FastRPC fixes
Posted by Nickolay Goppen 1 month, 2 weeks ago
This series introduces fixes that make FastRPC on SDM660 work properly.
Currently only the calculator_example test passes on both ADSP and 
CDSP [1].
Also assign adsp_mem region to the ADSP's FastRPC node.
