Merge branch 'pci/controller/qcom-ep'
- Log unknown Qcom Endpoint IRQ events at error level, not debug level
(Manivannan Sadhasivam)
- Add DT and driver support for qcom interconnect bandwidth voting for
"pcie-mem" and "cpu-pcie" interconnects (Krishna chaitanya chundru)
* pci/controller/qcom-ep:
PCI: qcom-ep: Add ICC bandwidth voting support
dt-bindings: PCI: qcom: ep: Add interconnects path
PCI: qcom-ep: Treat unknown IRQ events as an error
