Merge branch 'pci/misc' (2024-05-16 18:14:14 -0500)
----------------------------------------------------------------
Enumeration:
- Skip E820 checks for MCFG ECAM regions for new (2016+) machines, since
there's no requirement to describe them in E820 and some platforms
require ECAM to work (Bjorn Helgaas)
- Rename PCI_IRQ_LEGACY to PCI_IRQ_INTX to be more specific (Damien Le
Moal)
- Remove last user and pci_enable_device_io() (Heiner Kallweit)
- Wait for Link Training==0 to avoid possible race (Ilpo Järvinen)
- Skip waiting for devices that have been disconnected while suspended
(Ilpo Järvinen)
- Clear Secondary Status errors after enumeration since Master Aborts and
Unsupported Request errors are an expected part of enumeration (Vidya
Sagar)
MSI:
- Remove unused IMS (Interrupt Message Store) support (Bjorn Helgaas)
Error handling:
- Mask Genesys GL975x SD host controller Replay Timer Timeout correctable
errors caused by a hardware defect; the errors cause interrupts that
prevent system suspend (Kai-Heng Feng)
- Fix EDR-related _DSM support, which previously evaluated revision 5 but
assumed revision 6 behavior (Kuppuswamy Sathyanarayanan)
ASPM:
- Simplify link state definitions and mask calculation (Ilpo Järvinen)
Power management:
- Avoid D3cold for HP Pavilion 17 PC/1972 PCIe Ports, where BIOS
apparently doesn't know how to put them back in D0 (Mario Limonciello)
CXL:
- Support resetting CXL devices; special handling required because CXL
Ports mask Secondary Bus Reset by default (Dave Jiang)
DOE:
- Support DOE Discovery Version 2 (Alexey Kardashevskiy)
Endpoint framework:
- Set endpoint BAR to be 64-bit if the driver says that's all the device
supports, in addition to doing so if the size is >2GB (Niklas Cassel)
- Simplify endpoint BAR allocation and setting interfaces (Niklas Cassel)
Cadence PCIe controller driver:
- Drop DT binding redundant msi-parent and pci-bus.yaml (Krzysztof
Kozlowski)
Cadence PCIe endpoint driver:
- Configure endpoint BARs to be 64-bit based on the BAR type, not the BAR
value (Niklas Cassel)
Freescale Layerscape PCIe controller driver:
- Convert DT binding to YAML (Frank Li)
MediaTek MT7621 PCIe controller driver:
- Add DT binding missing 'reg' property for child Root Ports (Krzysztof
Kozlowski)
- Fix theoretical string truncation in PHY name (Sergio Paracuellos)
NVIDIA Tegra194 PCIe controller driver:
- Return success for endpoint probe instead of falling through to the
failure path (Vidya Sagar)
Renesas R-Car PCIe controller driver:
- Add DT binding missing IOMMU properties (Geert Uytterhoeven)
- Add DT binding R-Car V4H compatible for host and endpoint mode
(Yoshihiro Shimoda)
Rockchip PCIe controller driver:
- Configure endpoint BARs to be 64-bit based on the BAR type, not the BAR
value (Niklas Cassel)
- Add DT binding missing maxItems to ep-gpios (Krzysztof Kozlowski)
- Set the Subsystem Vendor ID, which was previously zero because it was
masked incorrectly (Rick Wertenbroek)
Synopsys DesignWare PCIe controller driver:
- Restructure DBI register access to accommodate devices where this
requires Refclk to be active (Manivannan Sadhasivam)
- Remove the deinit() callback, which was only need by the
pcie-rcar-gen4, and do it directly in that driver (Manivannan
Sadhasivam)
- Add dw_pcie_ep_cleanup() so drivers that support PERST# can clean up
things like eDMA (Manivannan Sadhasivam)
- Rename dw_pcie_ep_exit() to dw_pcie_ep_deinit() to make it parallel to
dw_pcie_ep_init() (Manivannan Sadhasivam)
- Rename dw_pcie_ep_init_complete() to dw_pcie_ep_init_registers() to
reflect the actual functionality (Manivannan Sadhasivam)
- Call dw_pcie_ep_init_registers() directly from all the glue drivers,
not just those that require active Refclk from the host (Manivannan
Sadhasivam)
- Remove the "core_init_notifier" flag, which was an obscure way for glue
drivers to indicate that they depend on Refclk from the host
(Manivannan Sadhasivam)
TI J721E PCIe driver:
- Add DT binding J784S4 SoC Device ID (Siddharth Vadapalli)
- Add DT binding J722S SoC support (Siddharth Vadapalli)
TI Keystone PCIe controller driver:
- Add DT binding missing num-viewport, phys and phy-name properties (Jan
Kiszka)
Miscellaneous:
- Constify and annotate with __ro_after_init (Heiner Kallweit)
- Convert DT bindings to YAML (Krzysztof Kozlowski)
- Check for kcalloc() failure in of_pci_prop_intr_map() (Duoming Zhou)
