Merge branch 'pci/misc' (2024-01-15 12:10:41 -0600)
----------------------------------------------------------------
Enumeration:
- Reserve ECAM so we don't assign it to PCI BARs; this works around bugs
where BIOS included ECAM in a PNP0A03 host bridge window, didn't
reserve it via a PNP0C02 motherboard device, and didn't allocate space
for SR-IOV VF BARs (Bjorn Helgaas)
- Add MMCONFIG/ECAM debug logging (Bjorn Helgaas)
- Rename 'MMCONFIG' to 'ECAM' to match spec usage (Bjorn Helgaas)
- Log device type (Root Port, Switch Port, etc) during enumeration (Bjorn
Helgaas)
- Log bridges before downstream devices so the dmesg order is more
logical (Bjorn Helgaas)
- Log resource names (BAR 0, VF BAR 0, bridge window, etc) consistently
instead of a mix of names and "reg 0x10" (Puranjay Mohan, Bjorn
Helgaas)
- Fix 64GT/s effective data rate calculation to use 1b/1b encoding rather
than the 8b/10b or 128b/130b used by lower rates (Ilpo Järvinen)
- Use PCI_HEADER_TYPE_* instead of literals in x86, powerpc, SCSI lpfc
(Ilpo Järvinen)
- Clean up open-coded PCIBIOS return code mangling (Ilpo Järvinen)
Resource management:
- Restructure pci_dev_for_each_resource() to avoid computing the address
of an out-of-bounds array element (the bounds check was performed later
so the element was never actually *read*, but it's nicer to avoid even
computing an out-of-bounds address) (Andy Shevchenko)
Driver binding:
- Convert pci-host-common.c platform .remove() callback to .remove_new()
returning 'void' since it's not useful to return error codes here (Uwe
Kleine-König)
- Convert exynos, keystone, kirin from .remove() to .remove_new(), which
returns void instead of int (Uwe Kleine-König)
- Drop unused struct pci_driver.node member (Mathias Krause)
Virtualization:
- Add ACS quirk for more Zhaoxin Root Ports (LeoLiuoc)
Error handling:
- Log AER errors as "Correctable" (not "Corrected") or "Uncorrectable" to
match spec terminology (Bjorn Helgaas)
- Decode Requester ID when no error info found instead of printing the
raw hex value (Bjorn Helgaas)
Endpoint framework:
- Use a unique test pattern for each BAR in the pci_endpoint_test to make
it easier to debug address translation issues (Niklas Cassel)
Broadcom STB PCIe controller driver:
- Add DT property "brcm,clkreq-mode" and driver support for different
CLKREQ# modes to make ASPM L1.x states possible (Jim Quinlan)
Freescale Layerscape PCIe controller driver:
- Add suspend/resume support for Layerscape LS1043a and LS1021a,
including software-managed PME_Turn_Off and transitions between L0,
L2/L3_Ready Link states (Frank Li)
MediaTek PCIe controller driver:
- Clear MSI interrupt status before handler to avoid missing MSIs that
occur after the handler (qizhong cheng)
MediaTek PCIe Gen3 controller driver:
- Update mediatek-gen3 translation window setup to handle MMIO space that
is not a power of two in size (Jianjun Wang)
Qualcomm PCIe controller driver:
- Increase qcom iommu-map maxItems to accommodate SDX55 (five entries)
and SDM845 (sixteen entries) (Krzysztof Kozlowski)
- Describe qcom,pcie-sc8180x clocks and resets accurately (Krzysztof
Kozlowski)
- Describe qcom,pcie-sm8150 clocks and resets accurately (Krzysztof
Kozlowski)
- Correct the qcom "reset-name" property, previously incorrectly called
"reset-names" (Krzysztof Kozlowski)
- Document qcom,pcie-sm8650, based on qcom,pcie-sm8550 (Neil Armstrong)
Renesas R-Car PCIe controller driver:
- Replace of_device.h with explicit of.h include to untangle header usage
(Rob Herring)
- Add DT and driver support for optional miniPCIe 1.5v and 3.3v
regulators on KingFisher (Wolfram Sang)
SiFive FU740 PCIe controller driver:
- Convert fu740 CONFIG_PCIE_FU740 dependency from SOC_SIFIVE to
ARCH_SIFIVE (Conor Dooley)
Synopsys DesignWare PCIe controller driver:
- Align iATU mapping for endpoint MSI-X (Niklas Cassel)
- Drop "host_" prefix from struct dw_pcie_host_ops members (Yoshihiro
Shimoda)
- Drop "ep_" prefix from struct dw_pcie_ep_ops members (Yoshihiro
Shimoda)
- Rename struct dw_pcie_ep_ops.func_conf_select() to .get_dbi_offset() to
be more descriptive (Yoshihiro Shimoda)
- Add Endpoint DBI accessors to encapsulate offset lookups (Yoshihiro
Shimoda)
TI J721E PCIe driver:
- Add j721e DT and driver support for 'num-lanes' for devices that
support x1, x2, or x4 Links (Matt Ranostay)
- Add j721e DT compatible strings and driver support for j784s4 (Matt
Ranostay)
- Make TI J721E Kconfig depend on ARCH_K3 since the hardware is specific
to those TI SoC parts (Peter Robinson)
TI Keystone PCIe controller driver:
- Hold power management references to all PHYs while enabling them to
avoid a race when one provides clocks to others (Siddharth Vadapalli)
Xilinx XDMA PCIe controller driver:
- Remove redundant dev_err(), since platform_get_irq() and
platform_get_irq_byname() already log errors (Yang Li)
- Fix uninitialized symbols in xilinx_pl_dma_pcie_setup_irq() (Krzysztof
Wilczyński)
- Fix xilinx_pl_dma_pcie_init_irq_domain() error return when
irq_domain_add_linear() fails (Harshit Mogalapalli)
MicroSemi Switchtec management driver:
- Do dma_mrpc cleanup during switchtec_pci_remove() to match its devm
ioremapping in switchtec_pci_probe(). Previously the cleanup was done
in stdev_release(), which used stale pointers if stdev->cdev happened
to be open when the PCI device was removed (Daniel Stodden)
Miscellaneous:
- Convert interrupt terminology from "legacy" to "INTx" to be more
specific and match spec terminology (Damien Le Moal)
- In dw-xdata-pcie, pci_endpoint_test, and vmd, replace usage of
deprecated ida_simple_*() API with ida_alloc() and ida_free()
(Christophe JAILLET)
