From: Kyle Deng <quic_chunk...@quicinc.com>
The Shared Memory Point to Point (SMP2P) protocol facilitates
communication of a single 32-bit value between two processors.
Add these two nodes for remoteproc enablement on QCS615 SoC.

There is already a description for this block above what you added
qcom,ipc under smp2p is mutually exclusive with `mboxes`, so adding
the above isn't necessary at all
Konrad
Understood, I will remove the qcom,ipc in next patch.
