a34cc7bf10 drm: Allow the caller to pass in the format info to drm_helper_mode_fill_fb_struct()
Soon all drivers should have the format info already available in the
places where they call drm_helper_mode_fill_fb_struct(). Allow it to
be passed along into drm_helper_mode_fill_fb_struct() instead of doing
yet another redundant lookup.

Start by always passing in NULL and still doing the extra lookup.
The actual changes to avoid the lookup will follow.

Done with cocci (with some manual fixups):

0e7d5874fb drm: Pass pixel_format+modifier directly to drm_get_format_info()
Decouple drm_get_format_info() from struct drm_mode_fb_cmd2 and just
pass the pixel format+modifier combo in by hand.

We may want to use drm_get_format_info() outside of the normal
addfb paths where we won't have a struct drm_mode_fb_cmd2, and
creating a temporary one just for this seems silly.

fff8e05044 drm/radeon: Do not hold console lock during resume
The function radeon_resume_kms() acquires the console lock. It is
inconsistent, as it depends on the notify_client argument. That
lock then covers a number of suspend operations that are unrelated
to the console.

Remove the calls to console_lock() and console_unlock() from the
radeon function. The console lock is only required by DRM's fbdev
emulation, which acquires it as necessary.

Also fixes a possible circular dependency between the console lock
and the client-list mutex, where the mutex is supposed to be taken
first.

612ec7c69d drm/radeon: Do not hold console lock while suspending clients
The radeon driver holds the console lock while suspending in-kernel
DRM clients. This creates a circular dependency with the client-list
mutex, which is supposed to be acquired first. Reported when combining
radeon with another DRM driver.

Therefore, do not take the console lock in radeon, but let the fbdev
DRM client acquire the lock when needed. This is what all other DRM
drivers so.

Merge tag 'pci-v6.16-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci

Pull pci updates from Bjorn Helgaas:
 "Enumeration:

   - Print the actual delay time in pci_bridge_wait_for_secondary_bus()
     instead of assuming it was 1000ms (Wilfred Mallawa)

   - Revert 'iommu/amd: Prevent binding other PCI drivers to IOMMU PCI
     devices', which broke resume from system sleep on AMD platforms and
     has been fixed by other commits (Lukas Wunner)

  Resource management:

   - Remove mtip32xx use of pcim_iounmap_regions(), which is deprecated
     and unnecessary (Philipp Stanner)

   - Remove pcim_iounmap_regions() and pcim_request_region_exclusive()
     and related flags since all uses have been removed (Philipp
     Stanner)

   - Rework devres 'request' functions so they are no longer 'hybrid',
     i.e., their behavior no longer depends on whether
     pcim_enable_device or pci_enable_device() was used, and remove
     related code (Philipp Stanner)

   - Warn (not BUG()) about failure to assign optional resources (Ilpo
     Järvinen)

  Error handling:

   - Log the DPC Error Source ID only when it's actually valid (when
     ERR_FATAL or ERR_NONFATAL was received from a downstream device)
     and decode into bus/device/function (Bjorn Helgaas)

   - Determine AER log level once and save it so all related messages
     use the same level (Karolina Stolarek)

   - Use KERN_WARNING, not KERN_ERR, when logging PCIe Correctable
     Errors (Karolina Stolarek)

   - Ratelimit PCIe Correctable and Non-Fatal error logging, with sysfs
     controls on interval and burst count, to avoid flooding logs and
     RCU stall warnings (Jon Pan-Doh)

  Power management:

   - Increment PM usage counter when probing reset methods so we don't
     try to read config space of a powered-off device (Alex Williamson)

   - Set all devices to D0 during enumeration to ensure ACPI opregion is
     connected via _REG (Mario Limonciello)

  Power control:

   - Rename pwrctrl Kconfig symbols from 'PWRCTL' to 'PWRCTRL' to match
     the filename paths. Retain old deprecated symbols for
     compatibility, except for the pwrctrl slot driver
     (PCI_PWRCTRL_SLOT) (Johan Hovold)

   - When unregistering pwrctrl, cancel outstanding rescan work before
     cleaning up data structures to avoid use-after-free issues (Brian
     Norris)

  Bandwidth control:

   - Simplify link bandwidth controller by replacing the count of Link
     Bandwidth Management Status (LBMS) events with a PCI_LINK_LBMS_SEEN
     flag (Ilpo Järvinen)

   - Update the Link Speed after retraining, since the Link Speed may
     have changed (Ilpo Järvinen)

  PCIe native device hotplug:

   - Ignore Presence Detect Changed caused by DPC.

     pciehp already ignores Link Down/Up events caused by DPC, but on
     slots using in-band presence detect, DPC causes a spurious Presence
     Detect Changed event (Lukas Wunner)

   - Ignore Link Down/Up caused by Secondary Bus Reset.

     On hotplug ports using in-band presence detect, the reset causes a
     Presence Detect Changed event, which mistakenly caused teardown and
     re-enumeration of the device. Drivers may need to annotate code
     that resets their device (Lukas Wunner)

  Virtualization:

   - Add an ACS quirk for Loongson Root Ports that don't advertise ACS
     but don't allow peer-to-peer transactions between Root Ports; the
     quirk allows each Root Port to be in a separate IOMMU group (Huacai
     Chen)

  Endpoint framework:

   - For fixed-size BARs, retain both the actual size and the possibly
     larger size allocated to accommodate iATU alignment requirements
     (Jerome Brunet)

   - Simplify ctrl/SPAD space allocation and avoid allocating more space
     than needed (Jerome Brunet)

   - Correct MSI-X PBA offset calculations for DesignWare and Cadence
     endpoint controllers (Niklas Cassel)

   - Align the return value (number of interrupts) encoding for
     pci_epc_get_msi()/pci_epc_ops::get_msi() and
     pci_epc_get_msix()/pci_epc_ops::get_msix() (Niklas Cassel)

   - Align the nr_irqs parameter encoding for
     pci_epc_set_msi()/pci_epc_ops::set_msi() and
     pci_epc_set_msix()/pci_epc_ops::set_msix() (Niklas Cassel)

  Common host controller library:

   - Convert pci-host-common to a library so platforms that don't need
     native host controller drivers don't need to include these helper
     functions (Manivannan Sadhasivam)

  Apple PCIe controller driver:

   - Extract ECAM bridge creation helper from pci_host_common_probe() to
     separate driver-specific things like MSI from PCI things (Marc
     Zyngier)

   - Dynamically allocate RID-to_SID bitmap to prepare for SoCs with
     varying capabilities (Marc Zyngier)

   - Skip ports disabled in DT when setting up ports (Janne Grunau)

   - Add t6020 compatible string (Alyssa Rosenzweig)

   - Add T602x PCIe support (Hector Martin)

   - Directly set/clear INTx mask bits because T602x dropped the
     accessors that could do this without locking (Marc Zyngier)

   - Move port PHY registers to their own reg items to accommodate
     T602x, which moves them around; retain default offsets for existing
     DTs that lack phy%d entries with the reg offsets (Hector Martin)

   - Stop polling for core refclk, which doesn't work on T602x and the
     bootloader has already done anyway (Hector Martin)

   - Use gpiod_set_value_cansleep() when asserting PERST# in probe
     because we're allowed to sleep there (Hector Martin)

  Cadence PCIe controller driver:

   - Drop a runtime PM 'put' to resolve a runtime atomic count underflow
     (Hans Zhang)

   - Make the cadence core buildable as a module (Kishon Vijay Abraham I)

   - Add cdns_pcie_host_disable() and cdns_pcie_ep_disable() for use by
     loadable drivers when they are removed (Siddharth Vadapalli)

  Freescale i.MX6 PCIe controller driver:

   - Apply link training workaround only on IMX6Q, IMX6SX, IMX6SP
     (Richard Zhu)

   - Remove redundant dw_pcie_wait_for_link() from
     imx_pcie_start_link(); since the DWC core does this, imx6 only
     needs it when retraining for a faster link speed (Richard Zhu)

   - Toggle i.MX95 core reset to align with PHY powerup (Richard Zhu)

   - Set SYS_AUX_PWR_DET to work around i.MX95 ERR051624 erratum: in
     some cases, the controller can't exit 'L23 Ready' through Beacon or
     PERST# deassertion (Richard Zhu)

   - Clear GEN3_ZRXDC_NONCOMPL to work around i.MX95 ERR051586 erratum:
     controller can't meet 2.5 GT/s ZRX-DC timing when operating at 8
     GT/s, causing timeouts in L1 (Richard Zhu)

   - Wait for i.MX95 PLL lock before enabling controller (Richard Zhu)

   - Save/restore i.MX95 LUT for suspend/resume (Richard Zhu)

  Mobiveil PCIe controller driver:

   - Return bool (not int) for link-up check in
     mobiveil_pab_ops.link_up() and layerscape-gen4, mobiveil (Hans
     Zhang)

  NVIDIA Tegra194 PCIe controller driver:

   - Create debugfs directory for 'aspm_state_cnt' only when
     CONFIG_PCIEASPM is enabled, since there are no other entries (Hans
     Zhang)

  Qualcomm PCIe controller driver:

   - Add OF support for parsing DT 'eq-presets-<N>gts' property for lane
     equalization presets (Krishna Chaitanya Chundru)

   - Read Maximum Link Width from the Link Capabilities register if DT
     lacks 'num-lanes' property (Krishna Chaitanya Chundru)

   - Add Physical Layer 64 GT/s Capability ID and register offsets for
     8, 32, and 64 GT/s lane equalization registers (Krishna Chaitanya
     Chundru)

   - Add generic dwc support for configuring lane equalization presets
     (Krishna Chaitanya Chundru)

   - Add DT and driver support for PCIe on IPQ5018 SoC (Nitheesh Sekar)

  Renesas R-Car PCIe controller driver:

   - Describe endpoint BAR 4 as being fixed size (Jerome Brunet)

   - Document how to obtain R-Car V4H (r8a779g0) controller firmware
     (Yoshihiro Shimoda)

  Rockchip PCIe controller driver:

   - Reorder rockchip_pci_core_rsts because
     reset_control_bulk_deassert() deasserts in reverse order, to fix a
     link training regression (Jensen Huang)

   - Mark RK3399 as being capable of raising INTx interrupts (Niklas
     Cassel)

  Rockchip DesignWare PCIe controller driver:

   - Check only PCIE_LINKUP, not LTSSM status, to determine whether the
     link is up (Shawn Lin)

   - Increase N_FTS (used in L0s->L0 transitions) and enable ASPM L0s
     for Root Complex and Endpoint modes (Shawn Lin)

   - Hide the broken ATS Capability in rockchip_pcie_ep_init() instead
     of rockchip_pcie_ep_pre_init() so it stays hidden after PERST#
     resets non-sticky registers (Shawn Lin)

   - Call phy_power_off() before phy_exit() in rockchip_pcie_phy_deinit()
     (Diederik de Haas)

  Synopsys DesignWare PCIe controller driver:

   - Set PORT_LOGIC_LINK_WIDTH to one lane to make initial link training
     more robust; this will not affect the intended link width if all
     lanes are functional (Wenbin Yao)

   - Return bool (not int) for link-up check in dw_pcie_ops.link_up()
     and armada8k, dra7xx, dw-rockchip, exynos, histb, keembay,
     keystone, kirin, meson, qcom, qcom-ep, rcar_gen4, spear13xx,
     tegra194, uniphier, visconti (Hans Zhang)

   - Add debugfs support for exposing DWC device-specific PTM context
     (Manivannan Sadhasivam)

  TI J721E PCIe driver:

   - Make j721e buildable as a loadable and removable module (Siddharth
     Vadapalli)

   - Fix j721e host/endpoint dependencies that result in link failures
     in some configs (Arnd Bergmann)

  Device tree bindings:

   - Add qcom DT binding for 'global' interrupt (PCIe controller and
     link-specific events) for ipq8074, ipq8074-gen3, ipq6018, sa8775p,
     sc7280, sc8180x sdm845, sm8150, sm8250, sm8350 (Manivannan
     Sadhasivam)

   - Add qcom DT binding for 8 MSI SPI interrupts for msm8998, ipq8074,
     ipq8074-gen3, ipq6018 (Manivannan Sadhasivam)

   - Add dw rockchip DT binding for rk3576 and rk3562 (Kever Yang)

   - Correct indentation and style of examples in brcm,stb-pcie,

     (Krzysztof Kozlowski)

   - Convert Marvell EBU (dove, kirkwood, armada-370, armada-xp) and
     armada8k from text to schema DT bindings (Rob Herring)

  Miscellaneous:

   - Drop 'pci' suffix from intel_mid_pci.c filename to match similar
     files (Andy Shevchenko)

   - All platforms with PCI have an MMU, so add PCI Kconfig dependency

8fe743b5eb PCI: Add CONFIG_MMU dependency
It turns out that there are no platforms that have PCI but don't have an
MMU, so adding a Kconfig dependency on CONFIG_PCI simplifies build testing
kernels for those platforms a lot, and avoids a lot of inadvertent build
regressions.

Add a dependency for CONFIG_PCI and remove all the ones for PCI specific
device drivers that are currently marked not having it.

There are a few platforms that have an optional MMU, but they usually
cannot have PCI at all. The one exception is Coldfire MCF54xx, but this is
mainly for historic reasons, and anyone using those chips should really use
the MMU these days.

fcbb93f1e4 drm/display: dp: change drm_dp_dpcd_read_link_status() return value
drm_dp_dpcd_read_link_status() follows the "return error code or number
of bytes read" protocol, with the code returning less bytes than
requested in case of some errors. However most of the drivers
interpreted that as "return error code in case of any error". Switch
drm_dp_dpcd_read_link_status() to drm_dp_dpcd_read_data() and make it
follow that protocol too.

2d52de55f9 drm/radeon: fix uninitialized size issue in radeon_vce_cs_parse()
On the off chance that command stream passed from userspace via
ioctl() call to radeon_vce_cs_parse() is weirdly crafted and
first command to execute is to encode (case 0x03000001), the function
in question will attempt to call radeon_vce_cs_reloc() with size
argument that has not been properly initialized. Specifically, 'size'
will point to 'tmp' variable before the latter had a chance to be
assigned any value.

Play it safe and init 'tmp' with 0, thus ensuring that
radeon_vce_cs_reloc() will catch an early error in cases like these.

189abca05a drm/radeon/ci_dpm: Remove needless NULL checks of dpm tables
This patch removes useless NULL pointer checks in functions like
ci_set_private_data_variables_based_on_pptable() and
ci_setup_default_dpm_tables().

The pointers in question are initialized as addresses to existing
structures such as rdev->pm.dpm.dyn_state.vddc_dependency_on_sclk by
utilizing & operator and therefore are not in danger of being NULL.

Fix this by removing extra checks thus cleaning the code a tiny bit.

7037bb0426 drm/radeon: Fix spurious unplug event on radeon HDMI
On several HP models (tested on HP 3125 and HP Probook 455 G2),
spurious unplug events are emitted upon login on Chrome OS.
This is likely due to the way Chrome OS restarts graphics
upon login, so it's possible it's an issue on other
distributions but not as common, though I haven't
reproduced the issue elsewhere.
Use logic from an earlier version of the merged change
(see link below) which iterates over connectors and finds
matching encoders, rather than the other way around.
Also fixes an issue with screen mirroring on Chrome OS.
I've deployed this patch on Fedora and did not observe
any regression on these devices.

88c79de857 drm/radeon: Suspend and resume clients with client helpers
Replace calls to radeon_fbdev_set_suspend() with calls to the client
functions drm_client_dev_suspend() and drm_client_dev_resume(). Any
registered in-kernel client will now receive suspend and resume events.

v4:
- refer to radeon_fbdev_set_suspend() in commit description (Jonathan)

3b6e7d4064 drm/radeon: Fix encoder->possible_clones
Include the encoder itself in its possible_clones bitmask.
In the past nothing validated that drivers were populating
possible_clones correctly, but that changed in commit
74d2aacbe8 ("drm: Validate encoder->possible_clones").
Looks like radeon never got the memo and is still not
following the rules 100% correctly.

This results in some warnings during driver initialization:
Bogus possible_clones: [ENCODER:46:TV-46] possible_clones=0x4 (full encoder mask=0x7)
WARNING: CPU: 0 PID: 170 at drivers/gpu/drm/drm_mode_config.c:615 drm_mode_config_validate+0x113/0x39c

fea5d61b80 drm/radeon: Use video aperture helpers
DRM's aperture functions have long been implemented as helpers
under drivers/video/ for use with fbdev. Avoid the DRM wrappers by
calling the video functions directly.

b4c1ad70e2 drm/radeon: add late_register for connector
The patch is to solve null dereference in 'aux.dev', which is
introduced in recent radeon rework. By having 'late_register',
the connector should be registered after 'drm_dev_register'
automatically, where in before it is the opposite.

a1e2da6a50 drm/radeon/r600_cs: Fix possible int overflow in r600_packet3_check()
It is possible, although unlikely, that an integer overflow will occur
when the result of radeon_get_ib_value() is shifted to the left.

Avoid it by casting one of the operands to larger data type (u64).
