Why do you redefine those ? they are already defined in the upstream sa8775p-ride-r3.dts
To include QCS9100 info to the model and compatible strings, so that users might not get confused if a wrong U-Boot has booted on the platform.
They are already defined in dts/upstream/src/arm64/qcom/sa8775p-ride-r3.dts
That file is patched at build time to include this dtsi file at the end.
Please let me know if this should still be removed.
Thanks Varada

Ack, this should be removed once the SMEM code is merged.

Why ? this file will be automatically appended to sa8775p-ride.dts, no need to import is before.

Same, unneeded.
In fact, this file is completely unneeded.
