  (Manivannan Sadhasivam)

- Add Qcom Endpoint eDMA support by enabling the eDMA IRQ (Manivannan

- Add Qcom Snapdragon SM8450 support to the EPF MHI driver (Manivannan
  Sadhasivam)

- Use iATU for EPF MHI transfers smaller than 4K to avoid eDMA setup
  latency (Manivannan Sadhasivam)

- Add pci_epc_mem_init() kernel-doc (Manivannan Sadhasivam)
