Merge branch 'pci/qcom'

- List platforms that use a single MSI host interrupt in qcom DT (Johan
  Hovold)

- Add SC8280XP, SA8540P support to qcom DT binding and driver(Johan Hovold)

- Make all optional clocks truly optional in the driver (Johan Hovold)

- Rename per-IP structs to reflect the IP version (Johan Hovold)

- Sort device ID match table by compatible string (Johan Hovold)

- Add MODULE_DEVICE_TABLE to enable module autoloading (Dmitry Baryshkov)

- Drop the unused .post_deinit() callback (Johan Hovold)

- Rely on DT for clock information instead of hard-coding it in the driver
  (Manivannan Sadhasivam)

- Disable IRQs when removing driver to avoid spurious IRQs later
  (Manivannan Sadhasivam)

- Expose link transition counts via debugfs to help debug issues with
  low-power states (Manivannan Sadhasivam)

- Gate Master AXI clock to the MHI bus while in L1 substates to save power
  (Manivannan Sadhasivam)

- Disable Master AXI clock to save power when there is no traffic on PCIe
  (Manivannan Sadhasivam)

- Make the "PERST separation" debug feature optional in the DT and the
  driver (Manivannan Sadhasivam)

- Define clocks to be per-platform in DT to prepare for future SoCs
  (Manivannan Sadhasivam)

- Add SM8450 SoC support (Manivannan Sadhasivam)

- Check for platform_get_resource_byname() to avoid a NULL pointer
  dereference (Yang Yingliang)
