Merge tag 'pci-v6.11-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci

Pull pci updates from Bjorn Helgaas:
"Enumeration:

- Define PCIE_RESET_CONFIG_DEVICE_WAIT_MS for the generic 100ms
required after reset before config access (Kevin Xie)

- Define PCIE_T_RRS_READY_MS for the generic 100ms required after
reset before config access (probably should be unified with
PCIE_RESET_CONFIG_DEVICE_WAIT_MS) (Damien Le Moal)

Resource management:

- Rename find_resource() to find_resource_space() to be more
descriptive (Ilpo Järvinen)

learn whether there is available space for a bridge window (Ilpo
Järvinen)

- Prevent double counting of resources so window size doesn't grow on
each remove/rescan cycle (Ilpo Järvinen)

- Relax bridge window sizing algorithm so a device doesn't break
simply because it was removed and rescanned (Ilpo Järvinen)

pci_register_host_bridge() (not acpi_pci_root_create()) so we can
unify it with similar DT functionality (Vidya Sagar)

per-host bridge as well as globally (Vidya Sagar)

"linux,pci-probe-only" property in pci_preserve_config() (Vidya
Sagar)

pci_request_region() and similar, which are sometimes managed

state (Philipp Stanner)

previously (Philipp Stanner)

prevents transactions between functions even though it doesn't
advertise ACS, so the functions can be attached individually via
VFIO (Ajit Khaparde)

Peer-to-peer DMA:

- Add a "pci=config_acs=" kernel command-line parameter to relax

dt-bindings: PCI: rockchip-dw-pcie: Fix description of legacy IRQ

The descriptions of the combined interrupt signals (level1) mention
all the lower interrupt signals (level2) for each combined interrupt,
regardless if the lower (level2) signal is RC or EP specific.

E.g. the description of "Combined system interrupt" includes rbar_update,
which is EP specific, and the description of "Combined message interrupt"
includes obff_idle, obff_obff, obff_cpu_active, which are all EP specific.

The only exception is the "Combined legacy interrupt", which for some
reason does not provide an exhaustive list of the lower (level2) signals.

Add the missing lower interrupt signals: tx_inta, tx_intb, tx_intc, and
tx_intd for the "Combined legacy interrupt", as per the rk3568 and rk3588
Technical Reference Manuals, such that the descriptions of the combined
interrupt signals are consistent.
