Re: [PATCH 2/3] arm64: dts: qcom: sm8550: add adsp, cdsp & mdss support nodes

This adds support for the aDSP, cDSP and MPSS Subsystems found in
the SM8550 SoC.

The aDSP, cDSP and MPSS needs:
- smp2p support nodes to get event back from the subsystems
- remoteproc nodes with glink-edge subnodes providing all needed
resources to start and run the subsystems

In addition, the MPSS Subsystem needs a rmtfs_mem dedicated
memory zone.

The title and commit message are misleading, you're either adding support or adding nodes. There is no such thing as "support nodes".

The code looks good though, so with that fixed:
