- Rename PCI_IRQ_LEGACY to PCI_IRQ_INTX to be more explicit and match spec
terminology (Bjorn Helgaas)
- Use existing PCI_IRQ_INTX, PCI_IRQ_MSI, PCI_IRQ_MSIX in artpec6, cadence,
designware, designware-plat, dra7xx, imx6, keembay, keystone, layerscape,
mhi, ntb, qcom, rcar, rcar-gen4, rockchip, tegra194, uniphier, vntb; drop
the redundant pci_epc_irq_type enum with the same values (Damien Le Moal)
- Use "intx" instead of "leg" or "legacy" when describing INTx interrupts
in endpoint core, endpoint tests, cadence, dra7xx, designware,
dw-rockchip, dwc core, imx6, keystone, layerscape, qcom, rcar-gen4,
rockchip, tegra194, uniphier, xilinx-nwl (Damien Le Moal)
* pci/irq-clean-up:
PCI: xilinx-nwl: Use INTX instead of legacy
PCI: rockchip-host: Rename rockchip_pcie_legacy_int_handler()
PCI: rockchip-ep: Use INTX instead of legacy
PCI: uniphier: Use INTX instead of legacy
PCI: tegra194: Use INTX instead of legacy
PCI: dw-rockchip: Rename rockchip_pcie_legacy_int_handler()
PCI: keystone: Use INTX instead of legacy
PCI: dwc: Rename dw_pcie_ep_raise_legacy_irq()
PCI: cadence: Use INTX instead of legacy
PCI: dra7xx: Rename dra7xx_pcie_raise_legacy_irq()
misc: pci_endpoint_test: Use INTX instead of LEGACY
PCI: endpoint: Rename LEGACY to INTX in test function driver
PCI: endpoint: Use INTX instead of legacy
PCI: endpoint: Drop PCI_EPC_IRQ_XXX definitions
PCI: Rename PCI_IRQ_LEGACY to PCI_IRQ_INTX
Since the name of the dw_pcie_host_ops struct makes it obvious that it's
for the PCIe Host, drop the host prefix from the struct members.

Rename the function rockchip_pcie_legacy_int_handler() to
rockchip_pcie_intx_handler() to match the code managing INTX interrupts
(e.g. intx_domain_ops) and the term used in the PCI specifications.

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus. As
part of that merge prepping Arm DT support 13 years ago, they "temporarily"
include each other. They also include platform_device.h and of.h. As a
result, there's a pretty much random mix of those include files used
throughout the tree. In order to detangle these headers and replace the
implicit includes with struct declarations, users need to explicitly
include the correct includes.

All of the DW PCIe core driver entities except the pcie_port struct have
names with the "dw_" prefix to distinguish local and common PCIe name
spaces, and endpoint-related entities have an "_ep" suffix.
Rename struct pcie_port to dw_pcie_rp to make it more consistent with other
names.

The legacy interrupts on the rk356x PCIe controller are handled by a
single muxed interrupt. Add IRQ domain support to the pcie-dw-rockchip
driver to support the virtual domain.

The PCIe controller is in an unknown state at driver probe. This can
lead to undesireable effects when the driver attempts to configure the
controller.
Prevent issues in the future by resetting the core during probe.

Add a driver for the DesignWare-based PCIe controller found on
RK356X. The existing pcie-rockchip-host driver is only used for
the Rockchip-designed IP found on RK3399.
