   4 Subject: [PATCH] arm64: dts: qcom: Add rpm-proc node for GLINK gplatforms
   5
   6 Rather than having the RPM GLINK channels as the only child of a dummy
   7 top-level rpm-glink node, switch to representing the RPM as remoteproc
   8 like all the other remoteprocs (modem DSP, ...).
   9
  10 This allows assigning additional subdevices to it like the MPM
  11 interrupt-controller or rpm-master-stats.
