Introduce a driver implementing Qualcomm Messaging Protocol (QMP) to
communicate with the Always On Subsystem (AOSS) and expose the low-power
states for the remoteprocs as a set of power-domains and the QDSS clock
as a clock.

Changes since v6:
- First couple of patches merged for v5.2
- Squashed the qmp and qmp-pd driver into one and by that moved it all
  to one file
- Expose QDSS clock as a clock instead of a power domain

Bjorn Andersson (3):
  dt-bindings: soc: qcom: Add AOSS QMP binding
  soc: qcom: Add AOSS QMP driver
  arm64: dts: qcom: Add AOSS QMP node

Sibi Sankar (1):
  arm64: dts: qcom: sdm845: Add Q6V5 MSS node
