PCI: aardvark: Implement emulated root PCI bridge config space

2018-10-18T16:51:41+00:00

The PCI controller in the Marvell Armada 3720 does not implement a software-accessible root port PCI bridge configuration space. This causes a number of problems when using PCIe switches or when the Max Payload size needs to be aligned between the root complex and the endpoint. Implementing an emulated root PCI bridge, like is already done in the pci-mvebu driver for older Marvell platforms allows to solve those issues, and also to support features such as ASR, PME, VC, HP.

PCI: mediatek: Add loadable kernel module support

2018-10-17T14:37:29+00:00

Implement remove() callback function for the Mediatek PCIe controller driver to add loadable kernel module support. Save the PCIe's GIC IRQ at probe so that it can be retrieved to call dispose_irq() to tear down the IRQ upon module removal.

PCI/xilinx: Depend on OF instead of the ARCH

2018-08-06T10:39:08+00:00

There isn't a hard dependency of the Xilinx AXI-PCIe host bridge on any architecture. For example: at SiFive we map RISC-V cores to Xilinx FPGAs and connect the Xilinx IP via a TileLink adapter, so the RISC-V Linux port will need to be able to enable PCIE_XILINX in order to have PCIe support. This patch decouples the PCIE_XILINX support from ARCH. Instead it just depends on OF, which is the only true dependency.

PCI: mobiveil: Add Kconfig/Makefile entries

2018-07-30T13:30:16+00:00

commit 9af6bcb11e12 ("PCI: mobiveil: Add Mobiveil PCIe Host Bridge IP driver") did not add the configuration and build infrastructure to configure and build the mobiveil controller driver, so at present the driver code is in the kernel but cannot be compiled. Add the mobiveil controller driver Kconfig/Makefile infrastructure.

PCI: controller: Move PCI_DOMAINS selection to arch Kconfig

2018-06-26T20:37:37+00:00

Commit 51bc085d6454 ("PCI: Improve host drivers compile test coverage") added configuration options to allow PCI host controller drivers to be compile tested on all architectures. Some host controller drivers (eg PCIE_ALTERA) config entries select the PCI_DOMAINS config option to enable PCI domains management in the kernel. Now that host controller drivers can be compiled on all architectures, this triggers build regressions on arches that do not implement the PCI_DOMAINS required API (ie pci_domain_nr()): drivers/ata/pata_ali.c: In function 'ali_init_chipset': drivers/ata/pata_ali.c:469:38: error: implicit declaration of function 'pci_domain_nr'; did you mean 'pci_iomap_wc'? Furthemore, some software configurations (ie Jailhouse) require a PCI_DOMAINS enabled kernel to configure multiple host controllers without having an explicit dependency on the ARM platform on which they run. Make PCI_DOMAINS a visible configuration option on ARM so that software configurations that need it can manually select it and move the PCI_DOMAINS selection from PCI controllers configuration file to ARM sub-arch config entries that currently require it, fixing the issue.

PCI: Collect all native drivers under drivers/pci/controller/

2018-06-08T12:50:11+00:00

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.
