* PCI: Collect all native drivers under drivers/pci/controller/Shawn Lin2018-06-081-57/+0
| | | | | | | | | | | | | | | | | | Native PCI drivers for root complex devices were originally all in drivers/pci/host/. Some of these devices can also be operated in endpoint mode. Drivers for endpoint mode didn't seem to fit in the "host" directory, so we put both the root complex and endpoint drivers in per-device directories, e.g., drivers/pci/dwc/, drivers/pci/cadence/, etc. These per-device directories contain trivial Kconfig and Makefiles and clutter drivers/pci/. Make a new drivers/pci/controllers/ directory and collect all the device-specific drivers there. No functional change intended.

* PCI: dwc: Remove old MSI IRQs APIGustavo Pimentel2018-03-061-2/+1

* PCI: dwc: Move MSI IRQs allocation to IRQ domains hierarchical APIGustavo Pimentel2018-03-061-0/+1
| | | | | | | | | | | | | | | | | | | | | Implement a multiplexed IRQ domain hierarchy API in the pcie-designware host bridge driver that funnels all MSI IRQs into a single parent interrupt, moving away from the obsolete struct msi_controller based API. Although the old implementation API is still available, pcie-designware will now use the multiplexed IRQ domains hierarchical API. Remove all existing dwc based host bridges MSI IRQs handlers, in that the hierarchical API now handles MSI IRQs through the hierarchical/chained MSI domain implementation.

* PCI: Add SPDX GPL-2.0 to replace GPL v2 boilerplateBjorn Helgaas2018-01-281-5/+1
| | | | | | | | | | | Add SPDX GPL-2.0 to all PCI files that specified the GPL version 2 license. Remove the boilerplate GPL version 2 language, relying on the assertion in b24413180f56 ("License cleanup: add SPDX GPL-2.0 license identifier to files with no license") that the SPDX identifier may be used instead of the full boilerplate text.

* PCI: keystone: Use PCI_NUM_INTXBjorn Helgaas2017-08-161-3/+1
| | | | | | | | Switch from using custom MAX_LEGACY_IRQS and MAX_LEGACY_HOST_IRQS macros to the generic PCI_NUM_INTX definition for the number of INTx interrupts.

* PCI: dwc: all: Split struct pcie_port into host-only and core structuresKishon Vijay Abraham I2017-02-211-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | Keep only the host-specific members in struct pcie_port and move the common members (i.e common to both host and endpoint) to struct dw_pcie. This is in preparation for adding endpoint mode support to designware driver. While at that also fix checkpatch warnings.

* PCI: Move DesignWare IP support to new drivers/pci/dwc/ directoryKishon Vijay Abraham I2017-02-211-0/+63
Group all the PCI drivers that use DesignWare core in dwc directory. dwc IP is capable of operating in both host mode and device mode and keeping it inside the *host* directory is misleading.
