Subject: [PATCH v2 0/7] Qualcomm AOSS QMP side channel binding and driver

Add binding and driver for the QMP based side-channel communication mechanism
to the AOSS, which is used to control resources not exposed through the RPMh
interface.

Currently implemented is a genpd provider, but pending some improvements in the
thermal framework a cooling device will be added at a later point. Patch 7 is
an "RFC" for how we define and probe these cooling devices.

The remoteproc patches updates the MSS driver to vote for the necessary genpd
corners on SDM845.

Lastly patch 6 makes it possible to have a device on the amba bus where the
apb_pclk is controlled as part of a power-domain.

Bjorn Andersson (6):
  dt-bindings: soc: qcom: Add AOSS QMP binding
  soc: qcom: Add AOSS QMP communication driver
  soc: qcom: Add AOSS QMP genpd provider
  remoteproc: q6v5-mss: Active powerdomain for SDM845
  amba: Allow pclk to be controlled by power domain
  soc: qcom: aoss-qmp: Add cooling device support

Rajendra Nayak (1):
  remoteproc: q6v5-mss: Vote for rpmh power domains
