Merge branch 'pci/controller/dwc-qcom'

- Set max OPP during resume so DBI register accesses don't fail with NoC
  errors (Qiang Yu)

- Add pci_host_common_d3cold_possible() to determine whether downstream
  devices are already in D3hot and wakeup-enabled devices are capable of
  generating PME from D3cold (Krishna Chaitanya Chundru)

- Add a .get_ltssm() callback to get the LTSSM status without DBI, since
  DBI may be inaccessible after PME_Turn_Off (Krishna Chaitanya Chundru)

- Power down PHY via PARF_PHY_CTRL before disabling rails/clocks to avoid
  power leakage (Krishna Chaitanya Chundru)

- Decide whether suspend should put the link in L2 and power down using
  pci_host_common_d3cold_possible() instead of checking whether ASPM L1 is
  enabled (Krishna Chaitanya Chundru)

- Add qcom D3cold support to tear down interconnect bandwidth and OPP votes
  (Krishna Chaitanya Chundru)

- Handle unsupported mixed PERST#/PHY DT configurations, e.g., PHY in RP
  node while PERST# is in the RC node, but warn about the DT issue (Qiang
  Yu)

- Add pcie_encode_t_power_on() to encode L1SS T_POWER_ON fields (Krishna
  Chaitanya Chundru)

- Add dw_pcie_program_t_power_on() to program T_POWER_ON (Krishna Chaitanya
  Chundru)

- Program qcom T_POWER_ON based on DT 't-power-on-us' property in case
  hardware advertises incorrect values (Krishna Chaitanya Chundru)

- Disable ASPM L0s for SA8775P (Shawn Guo)

- Initialize DWC MSI lock for firmware-managed ECAM hosts, which don't use
  the dw_pcie_host_init() path that initializes the lock (Yadu M G)
