Merge branch 'icc-glymur' into icc-next 

Add interconnect dt-bindings and driver support for
Qualcomm's next gen compute SoC - Glymur.

* icc-glymur
  dt-bindings: interconnect: document the RPMh Network-On-Chip interconnect in Glymur SoC
  interconnect: qcom: icc-rpmh: increase MAX_PORTS to support four QoS ports
  interconnect: qcom: add glymur interconnect provider driver

description: |

  RPMh interconnect providers support system bandwidth requirements through

  RPMh hardware accelerators known as Bus Clock Manager (BCM). The provider is

  able to communicate with the BCM through the Resource State Coordinator (RSC)

  associated with each execution environment. Provider nodes must point to at

  least one RPMh device child node pertaining to their RSC and each provider

  can map to multiple RPMh resources.
