[PATCH v3 0/3] ARM: cleanup PCI specific configs

[PATCH v3 0/3] ARM: cleanup PCI specific configs

[Kishon Vijay Abraham I]

This series was initially sent to add support for two PCIe
ports in dra7. This included selecting PCI_DOMAINS config
in SOC_DRA7XX.

However from the review, PCI_DOMAINS can instead be selected
from ARCH_MULTIPLATFORM. This is fixed in this series along
with removing PCI_DOMAINS from other configs.

Since this series was initially sent to add support for
two PCIe ports in dra7, it has been tested to see if there
are regressions with 1 PCIe port. Though testing of 2 PCIe ports
is not done while sending this patch series, it has been verified
before in few of the customer boards.

Changes from v2:
*) v2 removed MIGHT_HAVE_PCI from platforms that are not
   ARCH_MULTIPLATFORM. Fixed it in this version

Changes from v1:
*) select PCI_DOMAINS config from ARCH_MULTIPLATFORM
*) Fix *MIGHT_HAVE_PCI* config from being selected redundantly

[PATCH v3 1/3] ARM: dts: DRA7: Add "linux, pci-domain" property for pci dt nodes

[Kishon Vijay Abraham I]

Since DRA7 has multiple PCIe Rootcomplex, add "linux,pci-domain"
property to assign a PCI domain number to each of the host
bridges.
