Merge branch 'remotes/lorenzo/pci/xgene' (2022-03-22 17:16:27 -0500)
----------------------------------------------------------------
Enumeration:
- Move the VGA arbiter from drivers/gpu to drivers/pci because it's
PCI-specific, not GPU-specific (Bjorn Helgaas)
- Select the default VGA device consistently whether it's enumerated
before or after VGA arbiter init, which fixes arches that enumerate PCI
devices late (Huacai Chen)
Resource management:
- Support BAR sizes up to 8TB (Dongdong Liu)
PCIe native device hotplug:
- Fix "Command Completed" tracking to avoid spurious timouts when
powering off empty slots (Liguang Zhang)
- Quirk Qualcomm devices that don't implement Command Completed
correctly, again to avoid spurious timeouts (Manivannan Sadhasivam)
Peer-to-peer DMA:
- Add Intel 3rd Gen Intel Xeon Scalable Processors to whitelist (Michael
J. Ruhl)
APM X-Gene PCIe controller driver:
- Revert generic DT parsing changes that broke some machines in the field
(Marc Zyngier)
Freescale i.MX6 PCIe controller driver:
- Allow controller probe to succeed even when no devices currently
present to allow hot-add later (Fabio Estevam)
- Enable power management on i.MX6QP (Richard Zhu)
- Assert CLKREQ# on i.MX8MM so enumeration doesn't hang when no device is
connected (Richard Zhu)
Marvell Aardvark PCIe controller driver:
- Fix MSI and MSI-X support (Marek Behún, Pali Rohár)
- Add support for ERR and PME interrupts (Pali Rohár)
Marvell MVEBU PCIe controller driver:
- Add DT binding and support for "num-lanes" (Pali Rohár)
- Add support for INTx interrupts (Pali Rohár)
Microsoft Hyper-V host bridge driver:
- Avoid unnecessary hypercalls when unmasking IRQs on ARM64 (Boqun Feng)
Qualcomm PCIe controller driver:
- Add SM8450 DT binding and driver support (Dmitry Baryshkov)
Renesas R-Car PCIe controller driver:
- Help the controller get to the L1 state since the hardware can't do it
on its own (Marek Vasut)
- Return PCI_ERROR_RESPONSE (~0) for reads that fail on PCIe (Marek Vasut)
SiFive FU740 PCIe controller driver:
- Drop redundant '-gpios' from DT GPIO lookup (Ben Dooks)
- Force 2.5GT/s for initial device probe (Ben Dooks)
Socionext UniPhier Pro5 controller driver:
- Add NX1 DT binding and driver support (Kunihiko Hayashi)
Synopsys DesignWare PCIe controller driver:
- Restore MSI configuration so MSI works after resume (Jisheng Zhang)
