60b3c27fb9 PCI: dwc: Rename struct pcie_port to dw_pcie_rp 
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.

e8aae154df PCI: rockchip-dwc: Add legacy interrupt support 
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.

431e7d2eec PCI: rockchip-dwc: Reset core at driver probe 
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.

0e898eb8df PCI: rockchip-dwc: Add Rockchip RK356X host controller driver 
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.
