Merge tag 'pci-v7.1-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci

Pull pci updates from Bjorn Helgaas:
"Enumeration:

- Allow TLP Processing Hints to be enabled for RCiEPs (George Abraham
P)

- Enable AtomicOps only if we know the Root Port supports them (Gerd
Bayer)

- Don't enable AtomicOps for RCiEPs since none of them need Atomic
Ops and we can't tell whether the Root Complex would support them
(Gerd Bayer)

- Leave Precision Time Measurement disabled until a driver enables it
to avoid PCIe errors (Mika Westerberg)

- Make pci_set_vga_state() fail if bridge doesn't support VGA
routing, i.e., PCI_BRIDGE_CTL_VGA is not writable, and return
errors to vga_get() callers including userspace via
/dev/vga_arbiter (Simon Richter)

- Validate max-link-speed from DT in j721e, brcmstb, mediatek-gen3,
rzg3s drivers (where the actual controller constraints are known),
and remove validation from the generic OF DT accessor (Hans Zhang)

- Remove pc110pad driver (no longer useful after 486 CPU support
removed) and no_pci_devices() (pc110pad was the last user) (Dmitry
Torokhov, Heiner Kallweit)

Resource management:

- Prevent assigning space to unimplemented bridge windows; previously
we mistakenly assumed prefetchable window existed and assigned
space and put a BAR there (Ahmed Naseef)

- Avoid shrinking bridge windows to fit in the initial Root Port
window; fixes one problem with devices with large BARs connected
via switches, e.g., Thunderbolt (Ilpo Järvinen)

- Pass full extent of empty space, not just the aligned space, to
resource_alignf callback so free space before the requested
alignment can be used (Ilpo Järvinen)

- Place small resources before larger ones for better utilization of
address space (Ilpo Järvinen)

- Fix alignment calculation for resource size larger than align,
e.g., bridge windows larger than the 1MB required alignment (Ilpo
Järvinen)

Reset:

- Update slot handling so all ARI functions are treated as being in
the same slot. They're all reset by Secondary Bus Reset, but
previously drivers of ARI functions that appeared to be on a
non-zero device weren't notified and fatal hardware errors could
result (Keith Busch)

- Make sysfs reset_subordinate hotplug safe to avoid spurious hotplug
events (Keith Busch)

- Hide Secondary Bus Reset ('bus') from sysfs reset_methods if masked
by CXL because it has no effect (Vidya Sagar)

- Avoid FLR for AMD NPU device, where it causes the device to hang
(Lizhi Hou)

Error handling:

- Clear only error bits in PCIe Device Status to avoid accidentally
clearing Emergency Power Reduction Detected (Shuai Xue)

- Check for AER errors even in devices without drivers (Lukas Wunner)

- Initialize ratelimit info so DPC and EDR paths log AER error
information (Kuppuswamy Sathyanarayanan)

Power control:

- Add UPD720201/UPD720202 USB 3.0 xHCI Host Controller .compatible so
generic pwrctrl driver can control it (Neil Armstrong)

Hotplug:

- Set LED_HW_PLUGGABLE for NPEM hotplug-capable ports so LED core
doesn't complain when setting brightness fails because the endpoint
is gone (Richard Cheng)

Peer-to-peer DMA:

- Allow wildcards in list of host bridges that support peer-to-peer
DMA between hierarchy domains and add all Google SoCs (Jacob
Moroni)

Endpoint framework:

- Advertise dynamic inbound mapping support in pci-epf-test and
update host pci_endpoint_test to skip doorbell testing if not
advertised by endpoint (Koichiro Den)

- Return 0, not remaining timeout, when MHI eDMA ops complete so
mhi_ep_ring_add_element() doesn't interpret non-zero as failure
(Daniel Hodges)

- Remove vntb and ntb duplicate resource teardown that leads to oops
when .allow_link() fails or .drop_link() is called (Koichiro Den)

- Disable vntb delayed work before clearing BAR mappings and
doorbells to avoid oops caused by doing the work after resources
have been torn down (Koichiro Den)

- Add a way to describe reserved subregions within BARs, e.g.,
platform-owned fixed register windows, and use it for the RK3588
BAR4 DMA ctrl window (Koichiro Den)

- Add BAR_DISABLED for BARs that will never be available to an EPF
driver, and change some BAR_RESERVED annotations to BAR_DISABLED
(Niklas Cassel)

- Add NTB .get_dma_dev() callback for cases where DMA API requires a
different device, e.g., vNTB devices (Koichiro Den)

- Add reserved region types for MSI-X Table and PBA so Endpoint
controllers can them as describe hardware-owned regions in a
BAR_RESERVED BAR (Manikanta Maddireddy)

- Make Tegra194/234 BAR0 programmable and remove 1MB size limit
(Manikanta Maddireddy)

- Expose Tegra BAR2 (MSI-X) and BAR4 (DMA) as 64-bit BAR_RESERVED
(Manikanta Maddireddy)

- Add Tegra194 and Tegra234 device table entries to pci_endpoint_test
(Manikanta Maddireddy)

- Skip the BAR subrange selftest if there are not enough inbound
window resources to run the test (Christian Bruel)

New native PCIe controller drivers:

- Add DT binding and driver for Andes QiLai SoC PCIe host controller
(Randolph Lin)

- Add DT binding and driver for ESWIN PCIe Root Complex (Senchuan
Zhang)

Baikal T-1 PCIe controller driver:

- Remove driver since it never quite became usable (Andy Shevchenko)

Cadence PCIe controller driver:

- Implement byte/word config reads with dword (32-bit) reads because
some Cadence controllers don't support sub-dword accesses (Aksh
Garg)

CIX Sky1 PCIe controller driver:

- Add 'power-domains' to DT binding for SCMI power domain (Gary Yang)

Freescale i.MX6 PCIe controller driver:

- Add i.MX94 and i.MX943 to fsl,imx6q-pcie-ep DT binding (Richard
Zhu)

- Delay instead of polling for L2/L3 Ready after PME_Turn_off when
suspending i.MX6SX because LTSSM registers are inaccessible
(Richard Zhu)

- Separate PERST# assertion (for resetting endpoints) from core reset
(for resetting the RC itself) to prepare for new DTs with PERST#
GPIO in per-Root Port nodes (Sherry Sun)

- Retain Root Port MSI capability on i.MX7D, i.MX8MM, and i.MX8MQ so
MSI from downstream devices will work (Richard Zhu)

- Fix i.MX95 reference clock source selection when internal refclk is
used (Franz Schnyder)

Freescale Layerscape PCIe controller driver:

- Allow building as a removable module (Sascha Hauer)

MediaTek PCIe Gen3 controller driver:

- Use dev_err_probe() to simplify error paths and make deferred probe
messages visible in /sys/kernel/debug/devices_deferred (Chen-Yu
Tsai)

- Power off device if setup fails (Chen-Yu Tsai)

- Integrate new pwrctrl API to enable power control for WiFi/BT
adapters on mainboard or in PCIe or M.2 slots (Chen-Yu Tsai)

NVIDIA Tegra194 PCIe controller driver:

- Poll less aggressively and non-atomically for PME_TO_Ack during
transition to L2 (Vidya Sagar)

- Disable LTSSM after transition to Detect on surprise link down to
stop toggling between Polling and Detect (Manikanta Maddireddy)

- Don't force the device into the D0 state before L2 when suspending
or shutting down the controller (Vidya Sagar)

- Disable PERST# IRQ only in Endpoint mode because it's not
registered in Root Port mode (Manikanta Maddireddy)

- Handle 'nvidia,refclk-select' as optional (Vidya Sagar)

- Disable direct speed change in Endpoint mode so link speed change
is controlled by the host (Vidya Sagar)

- Set LTR values before link up to avoid bogus LTR messages with 0
latency (Vidya Sagar)

- Allow system suspend when the Endpoint link is down (Vidya Sagar)

- Use DWC IP core version, not Tegra custom values, to avoid DWC core
version check warnings (Manikanta Maddireddy)

- Apply ECRC workaround to devices based on DesignWare 5.00a as well
as 4.90a (Manikanta Maddireddy)

- Disable PM Substate L1.2 in Endpoint mode to work around Tegra234
erratum (Vidya Sagar)

- Delay post-PERST# cleanup until core is powered on to avoid CBB
timeout (Manikanta Maddireddy)

- Assert CLKREQ# so switches that forward it to their downstream side
can bring up those links successfully (Vidya Sagar)

- Calibrate pipe to UPHY for Endpoint mode to reset stale PLL state
from any previous bad link state (Vidya Sagar)

- Remove IRQF_ONESHOT flag from Endpoint interrupt registration so
DMA driver and Endpoint controller driver can share the interrupt
line (Vidya Sagar)

- Enable DMA interrupt to support DMA in both Root Port and Endpoint
modes (Vidya Sagar)

- Enable hardware link retraining after link goes down in Endpoint
mode (Vidya Sagar)

- Add DT binding and driver support for core clock monitoring (Vidya
Sagar)

Qualcomm PCIe controller driver:

- Advertise 'Hot-Plug Capable' and set 'No Command Completed Support'
since Qcom Root Ports support hotplug events like DL_Up/Down and
can accept writes to Slot Control without delays between writes
(Krishna Chaitanya Chundru)

Renesas R-Car PCIe controller driver:

- Mark Endpoint BAR0 and BAR2 as Resizable (Koichiro Den)

- Reduce EPC BAR alignment requirement to 4K (Koichiro Den)

Renesas RZ/G3S PCIe controller driver:

- Add RZ/G3E to DT binding and to driver (John Madieu)

- Assert (not deassert) resets in probe error path (John Madieu)

- Assert resets in suspend path in reverse order they were deasserted
during probe (John Madieu)

Merge tag 'pci-v6.19-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci

Pull PCI updates from Bjorn Helgaas:
"Enumeration:

- Enable host bridge emulation for PCI_DOMAINS_GENERIC platforms (Dan
Williams)

- Switch vmd from custom domain number allocator to the common
allocator to prevent a potential race with new non-VMD buses (Dan
Williams)

- Enable Precision Time Measurement (PTM) only if device advertises
support for a relevant role, to prevent invalid PTM Requests that
cause ACS violations that are reported as AER Uncorrectable
Non-Fatal errors (Mika Westerberg)

Resource management:

- Prevent resource tree corruption when BAR resize fails (Ilpo
Järvinen)

- Restore BARs to the original size if a BAR resize fails (Ilpo
Järvinen)

- Remove BAR release from BAR resize attempts by the xe, i915, and
amdgpu drivers so the PCI core can restore BARs if the resize fails
(Ilpo Järvinen)

- Move Resizable BAR code to rebar.c (Ilpo Järvinen)

- Add pci_rebar_size_supported() and use it in i915 and xe (Ilpo
Järvinen)

- Add pci_rebar_get_max_size() and use it in xe and amdgpu (Ilpo
Järvinen)

Power management and error handling:

- For drivers using PCI legacy suspend, save config state at suspend
so that state (not any earlier state from enumeration, probe, or
error recovery) will be restored when resuming (Lukas Wunner)

- For devices with no driver or a driver that lacks power management,
save config state at hibernate so that state (not any earlier state
from enumeration, probe, or error recovery) will be restored when
resuming (Lukas Wunner)

- Save device config space on device addition, before driver binding,
so error recovery works more reliably (Lukas Wunner)

- Drop pci_save_state() from several drivers that no longer need it
since the PCI core always does it and pci_restore_state() no longer
invalidates the saved state (Lukas Wunner)

- Document use of pci_save_state() by drivers to capture the state
they want restored during error recovery (Lukas Wunner)

Power control:

- Add a struct pci_ops.assert_perst() function pointer to
assert/deassert PCIe PERST# and implement it for the qcom driver
(Krishna Chaitanya Chundru)

- Clear L1 PM Substate Capability 'Supported' bits unless glue driver
says it's supported, which prevents users from enabling non-working
L1SS. Currently only qcom and tegra194 support L1SS (Bjorn Helgaas)

- Remove now-superfluous L1SS disable code from tegra194 (Bjorn
Helgaas)

- Configure L1SS support in dw-rockchip when DT says

end

PCI: pwrctrl: Add power control driver for TC9563

TC9563 is a PCIe switch that has one upstream and three downstream ports.
One of the downstream ports is connected to an integrated ethernet MAC
endpoint. The other two downstream ports are available to connect to
external devices. One Host can connect to TC9563 by upstream port. The
TC9563 switch needs to be configured after powering on and before the PCIe
link is up.

The PCIe controller driver already enables link training at the host side
even before this driver probe happens. Due to this, when driver enables
power to the switch, it participates in link training and the PCIe link may
come up before configuring the switch through I2C. Once the link is up the
configuration done through I2C will not have any effect. To prevent the
host from participating in link training, disable link training on the host
side to ensure the link does not come up before the switch is configured
via I2C.

Based on DT property and type of the port, TC9563 is configured through
I2C.
