From 7e1acc8b92a3b67db1e5255adae2851d58d74434 Mon Sep 17 00:00:00 2001
From: Stephan Gerhold <stephan@gerhold.net>

Subject: [PATCH] arm64: dts: qcom: Add rpm-proc node for GLINK gplatforms
Rather than having the RPM GLINK channels as the only child of a dummy
top-level rpm-glink node, switch to representing the RPM as remoteproc
like all the other remoteprocs (modem DSP, ...).
This allows assigning additional subdevices to it like the MPM
interrupt-controller or rpm-master-stats.
