Merge branch 'pci/controller/qcom'

- Use devm_clk_bulk_get_all() to get all the clocks from DT to avoid
  writing out all the clock names (Manivannan Sadhasivam)

- Add DT binding and driver support for the SA8775P SoC (Mrinmay Sarkar)

- Refactor dw_pcie_edma_find_chip() to enable adding support for Hyper DMA
  (HDMA) (Manivannan Sadhasivam)

- Enable drivers to supply the eDMA channel count since some can't auto
  detect this (Manivannan Sadhasivam)

- Add HDMA support for the SA8775P SoC (Mrinmay Sarkar)

- Override the SA8775P NO_SNOOP default to avoid possible memory corruption
  (Mrinmay Sarkar)

- Make sure resources are disabled during PERST# assertion, even if the
  link is already disabled (Manivannan Sadhasivam)

- Vote for the CPU-PCIe ICC (interconnect) path to ensure it stays active
  even if other drivers don't vote for it (Krishna chaitanya chundru)

- Add Operating Performance Points (OPP) to scale performance state based
  on aggregate link bandwidth to improve SoC power efficiency (Krishna
  chaitanya chundru)

- Return failure instead of success if dev_pm_opp_find_freq_floor() fails
  (Dan Carpenter)

- Avoid an error pointer dereference if dev_pm_opp_find_freq_exact() fails
  (Dan Carpenter)

- Prevent use of uninitialized data in qcom_pcie_suspend_noirq() (Dan
  Carpenter)
