Subject: [RFC 0/3] Add interconnect support to the SCM interface

Some of the SMC calls required by remoteproc PAS driver on SM8450 SoCs
get a performance benefit from having a max vote to the crypto->ddr path.
Add support for bandwidth (bw) voting for those SMC calls when the
interconnects property is specified. Marking this as an RFC since the path
could either be specified in the individual remoteprocs or directly in the
scm interface.

Sibi Sankar (3):
  dt-bindings: firmware: qcom-scm: Add interconnects property
  firmware: qcom_scm: Add bw voting support to the SCM interface
  arm64: dts: qcom: sm8450: Add interconnect requirements for SCM
