Pull PCI updates from Bjorn Helgaas: - skip AER driver error recovery callbacks for correctable errors reported via ACPI APEI, as we already do for errors reported via the native path (Tyler Baicar) - fix DPC shared interrupt handling (Alex Williamson) - print full DPC interrupt number (Keith Busch) - enable DPC only if AER is available (Keith Busch) - simplify DPC code (Bjorn Helgaas) - calculate ASPM L1 substate parameter instead of hardcoding it (Bjorn Helgaas) - enable Latency Tolerance Reporting for ASPM L1 substates (Bjorn Helgaas) - move ASPM internal interfaces out of public header (Bjorn Helgaas) - allow hot-removal of VGA devices (Mika Westerberg) - speed up unplug and shutdown by assuming Thunderbolt controllers don't support Command Completed events (Lukas Wunner) - add AtomicOps support for GPU and Infiniband drivers (Felix Kuehling, Jay Cornwall) - expose "ari_enabled" in sysfs to help NIC naming (Stuart Hayes) - clean up PCI DMA interface usage (Christoph Hellwig) - remove PCI pool API (replaced with DMA pool) (Romain Perier) - deprecate pci_get_bus_and_slot(), which assumed PCI domain 0 (Sinan Kaya) - move DT PCI code from drivers/of/ to drivers/pci/ (Rob Herring) - add PCI-specific wrappers for dev_info(), etc (Frederick Lawler) - remove warnings on sysfs mmap failure (Bjorn Helgaas) - quiet ROM validation messages (Alex Deucher) - remove redundant memory alloc failure messages (Markus Elfring) - fill in types for compile-time VGA and other I/O port resources (Bjorn Helgaas) - make "pci=pcie_scan_all" work for Root Ports as well as Downstream Ports to help AmigaOne X1000 (Bjorn Helgaas) - add SPDX tags to all PCI files (Bjorn Helgaas) - quirk Marvell 9128 DMA aliases (Alex Williamson) - quirk broken INTx disable on Ceton InfiniTV4 (Bjorn Helgaas) - fix CONFIG_PCI=n build by adding dummy pci_irqd_intx_xlate() (Niklas Cassel) - use DMA API to get MSI address for DesignWare IP (Niklas Cassel) - fix endpoint-mode DMA mask configuration (Kishon Vijay Abraham I) - fix ARTPEC-6 incorrect IS_ERR() usage (Wei Yongjun) - add support for ARTPEC-7 SoC (Niklas Cassel) - add endpoint-mode support for ARTPEC (Niklas Cassel) - add Cadence PCIe host and endpoint controller driver (Cyrille Pitchen) - handle multiple INTx status bits being set in dra7xx (Vignesh R) - translate dra7xx hwirq range to fix INTD handling (Vignesh R) - remove deprecated Exynos PHY initialization code (Jaehoon Chung) - fix MSI erratum workaround for HiSilicon Hip06/Hip07 (Dongdong Liu) - fix NULL pointer dereference in iProc BCMA driver (Ray Jui) - fix Keystone interrupt-controller-node lookup (Johan Hovold) - constify qcom driver structures (Julia Lawall) - rework Tegra config space mapping to increase space available for endpoints (Vidya Sagar) - simplify Tegra driver by using bus->sysdata (Manikanta Maddireddy) - remove PCI_REASSIGN_ALL_BUS usage on Tegra (Manikanta Maddireddy) - add support for Global Fabric Manager Server (GFMS) event to Microsemi Switchtec switch driver (Logan Gunthorpe) - add IDs for Switchtec PSX 24xG3 and PSX 48xG3 (Kelvin Cao) * tag 'pci-v4.16-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci: (140 commits) PCI: cadence: Add EndPoint Controller driver for Cadence PCIe controller dt-bindings: PCI: cadence: Add DT bindings for Cadence PCIe endpoint controller PCI: endpoint: Fix EPF device name to support multi-function devices PCI: endpoint: Add the function number as argument to EPC ops PCI: cadence: Add host driver for Cadence PCIe controller dt-bindings: PCI: cadence: Add DT bindings for Cadence PCIe host controller PCI: Add vendor ID for Cadence PCI: Add generic function to probe PCI host controllers PCI: generic: fix missing call of pci_free_resource_list() PCI: OF: Add generic function to parse and allocate PCI resources PCI: Regroup all PCI related entries into drivers/pci/Makefile PCI/DPC: Reformat DPC register definitions PCI/DPC: Add and use DPC Status register field definitions PCI/DPC: Squash dpc_rp_pio_get_info() into dpc_process_rp_pio_error() PCI/DPC: Remove unnecessary RP PIO register structs PCI/DPC: Push dpc->rp_pio_status assignment into dpc_rp_pio_get_info() PCI/DPC: Squash dpc_rp_pio_print_error() into dpc_rp_pio_get_info() PCI/DPC: Make RP PIO log size check more generic PCI/DPC: Rename local "status" to "dpc_status" PCI/DPC: Squash dpc_rp_pio_print_tlp_header() into dpc_rp_pio_print_error() ...

PCI: Move OF-related PCI functions into PCI core

2018-01-17T23:36:39Z

Following what has been done for other subsystems, move the remaining PCI related code out of drivers/of/ and into drivers/pci/of.c With this, we can kill a few kconfig symbols. Signed-off-by: Rob Herring [bhelgaas: minor whitespace, comment cleanups] Signed-off-by: Bjorn Helgaas Cc: Frank Rowand

of: Export of_pci_range_to_resource()

2018-01-15T16:45:55Z

Some PCIe host drivers parse of_pci_range from device tree and convert it to resources. Export of_pci_range_to_resource() to allow PCIe host drivers to be compiled as loadable kernel module.

of/pci: Add of_pci_dma_range_parser_init() for dma-ranges parsing support

2017-10-05T20:52:34Z

Several host bridge drivers duplicate of_pci_range_parser_init() in order to parse their dma-ranges property. Provide of_pci_dma_range_parser_init() for that use case. Signed-off-by: Marc Gonzalez Signed-off-by: Bjorn Helgaas Reviewed-by: Rob Herring Reviewed-by: Linus Walleij

of: remove unused pci_space variable from address.c

2017-07-21T15:46:15Z

It was never used and could be removed, otherwise we could see a warning: drivers/of/address.c: In function 'of_pci_range_parser_one': drivers/of/address.c:277:14: warning: variable 'pci_space' set but not used [-Wunused-but-set-variable] Signed-off-by: Shawn Lin Signed-off-by: Rob Herring

of: Convert to using %pOF instead of full_name

2017-07-18T22:09:18Z

Now that we have a custom printf format specifier, convert users of full_name to use %pOF instead. This is preparation to remove storing of the full path string for each node. Signed-off-by: Rob Herring

of: fix sparse warning in of_pci_range_parser_one

2017-05-04T17:58:48Z

sparse gives the following warning for 'pci_space': ../drivers/of/address.c:266:26: warning: incorrect type in assignment (different base types) ../drivers/of/address.c:266:26: expected unsigned int [unsigned] [usertype] pci_space ../drivers/of/address.c:266:26: got restricted __be32 const [usertype] It appears that pci_space is only ever accessed on powerpc, so the endian swap is often not needed.
