7151202b64 rpmsg updates for v4.14
This extends the Qualcomm GLINK implementation to support the additional
 features used for communicating with modem and DSP coprocessors in modern
 Qualcomm platforms.
 
 In addition to this there's support for placing virtio RPMSG buffers in
 non-System RAM.

2b41d6c8e6 dt-bindings: soc: qcom: Extend GLINK to cover SMEM
In addition to using GLINK for communication with the RPM it can be
used ontop of SMEM for communicating with remoteprocs, extend the
binding to also describe this case and reference the GLINK binding from
the affected remoteproc bindings.

b4daf89057 remoteproc/keystone: Add support for Keystone 66AK2G SOCs
Add support to the keystone remoteproc driver for managing the
DSP present in the Keystone 2 66AK2G SoC. The 66AK2G SoC has
a Power Management Micro Controller (PMMC) that manages the
individual device's power, clock and reset functionalities.

The keystone remoteproc driver already uses standard frameworks
for reset and clock control, so it doesn't require any significant
modifications other than a new compatible suitable for 66AK2G DSP.

The binding document is also updated to reflect the modified
property values used by the 66AK2G DSP node as compared to the
values used by existing Keystone 2 DSPs.

MSS rproc loader need chip specific resources initialization during probe
to load and boot modem firmware, this need compatible string based
differentiation in resources to be initialized. This patch add and provide
a template struct whose fields represent all those resources which are
needed to load and boot modem fw and which may differ from chip to chip.
This patch also add new compatible string for msm8916, msm8974 platform.
