Add driver for Intel Keem Bay SoC PCIe controller. This controller is based on DesignWare PCIe core. In Root Complex mode, only internal reference clock is possible for Keem Bay A0. For Keem Bay B0, external reference clock can be used and will be the default configuration. Currently, keembay_pcie_of_data structure has one member. It will be expanded later to handle this difference. Endpoint mode link initialization is handled by the boot firmware.

2020-12-09PCI: qcom: Add support for configuring BDF to SID mapping for SM8250Manivannan Sadhasivam
For SM8250, we need to write the BDF to SID mapping in PCIe controller register space for proper working. This is accomplished by extracting the BDF and SID values from "iommu-map" property in DT and writing those in the register address calculated from the hash value of BDF. In case of collisions, the index of the next entry will also be written. For the sake of it, let's introduce a "config_sid" callback and do it conditionally for SM8250.

2019-09-16PCI: dwc: al: Add Amazon Annapurna Labs PCIe controller driverJonathan Chocron
This driver is DT based and utilizes the DesignWare APIs. It allows using a smaller ECAM range for a larger bus range - usually an entire bus uses 1MB of address space, but the driver can use it for a larger number of buses. This is achieved by using a HW mechanism which allows changing the BUS part of the "final" outgoing config transaction. There are 2 HW regs, one which is basically a bitmask determining which bits to take from the AXI transaction itself and another which holds the complementary part programmed by the driver. All link initializations are handled by the boot FW.

2018-06-08PCI: Collect all native drivers under drivers/pci/controller/Shawn Lin
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.
