Merge branch 'pci/driver-cleanup' (2022-01-13 09:57:53 -0600)

----------------------------------------------------------------

You should see the following conflicts:

drivers/pci/controller/Kconfig

44ddb791f8f4 ("PCI: mt7621: Allow COMPILE_TEST for all arches") enables
tristate again and removes arch dependencies; this conflicts with
aa50faff4416 ("PCI: mt7621: Convert driver into 'bool'"), which
appeared in v5.16-rc6

My resolution: https://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci.git/tree/drivers/pci/controller/Kconfig?h=v5.17-merge&id=868fafd67742#n334

argument to ti,syscon-pcie-mode; this conflicts with dcd49679fb3a
("dt-bindings: PCI: Fix 'unevaluatedProperties' warnings") from the
devicetree tree, which removed num-ib-windows, num-ob-windows
