ASoC: Fixes for v6.19

We've been quite busy with fixes since the merge window, though not in
any particularly exciting ways - the standout thing is the fix for _SX
controls which were broken by a change to how we do clamping, otherwise
it's all fairly run of the mill fixes and quirks.

Merge tag 'tsm-for-6.19' of git://git.kernel.org/pub/scm/linux/kernel/git/devsec/tsm

Pull PCIe Link Encryption and Device Authentication from Dan Williams:
"New PCI infrastructure and one architecture implementation for PCIe
link encryption establishment via platform firmware services.

This work is the result of multiple vendors coming to consensus on
some core infrastructure (thanks Alexey, Yilun, and Aneesh!), and
three vendor implementations, although only one is included in this
pull. The PCI core changes have an ack from Bjorn, the crypto/ccp/
changes have an ack from Tom, and the iommu/amd/ changes have an ack
from Joerg.

PCIe link encryption is made possible by the soup of acronyms
mentioned in the shortlog below. Link Integrity and Data Encryption
(IDE) is a protocol for installing keys in the transmitter and
receiver at each end of a link. That protocol is transported over Data
Object Exchange (DOE) mailboxes using PCI configuration requests.

The aspect that makes this a "platform firmware service" is that the
key provisioning and protocol is coordinated through a Trusted
Execution Envrionment (TEE) Security Manager (TSM). That is either
firmware running in a coprocessor (AMD SEV-TIO), or quasi-hypervisor
software (Intel TDX Connect / ARM CCA) running in a protected CPU
mode.

Now, the only reason to ask a TSM to run this protocol and install the
keys rather than have a Linux driver do the same is so that later, a
confidential VM can ask the TSM directly "can you certify this
device?".

That precludes host Linux from provisioning its own keys, because host
Linux is outside the trust domain for the VM. It also turns out that
all architectures, save for one, do not publish a mechanism for an OS
to establish keys in the root port. So "TSM-established link
encryption" is the only cross-architecture path for this capability
for the foreseeable future.

This unblocks the other arch implementations to follow in v6.20/v7.0,
once they clear some other dependencies, and it unblocks the next
phase of work to implement the end-to-end flow of confidential device
assignment. The PCIe specification calls this end-to-end flow Trusted
Execution Environment (TEE) Device Interface Security Protocol
(TDISP).

In the meantime, Linux gets a link encryption facility which has
practical benefits along the same lines as memory encryption. It
authenticates devices via certificates and may protect against
interposer attacks trying to capture clear-text PCIe traffic.

Summary:

- Introduce the PCI/TSM core for the coordination of device
authentication, link encryption and establishment (IDE), and later
management of the device security operational states (TDISP).
Notify the new TSM core layer of PCI device arrival and departure

- Add a low level TSM driver for the link encryption establishment
capabilities of the AMD SEV-TIO architecture

- Add a library of helpers TSM drivers to use for IDE establishment
and the DOE transport

- Add skeleton support for 'bind' and 'guest_request' operations in
support of TDISP"

PCI/TSM: Add 'dsm' and 'bound' attributes for dependent functions

PCI/TSM sysfs for physical function 0 devices, i.e. the "DSM" (Device
Security Manager), contains the 'connect' and 'disconnect' attributes.
After a successful 'connect' operation the DSM, its dependent functions
(SR-IOV virtual functions, non-zero multi-functions, or downstream
endpoints of a switch DSM) are candidates for being transitioned into a
TDISP (TEE Device Interface Security Protocol) operational state, via
pci_tsm_bind(). At present sysfs is blind to which devices are capable of
TDISP operation and it is ambiguous which functions are serviced by which
DSMs.

Add a 'dsm' attribute to identify a function's DSM device, and add a
'bound' attribute to identify when a function has entered a TDISP
operational state.

PCI/TSM: Establish Secure Sessions and Link Encryption

PCI/TSM: Establish Secure Sessions and Link Encryption

The PCIe 7.0 specification, section 11, defines the Trusted Execution
Environment (TEE) Device Interface Security Protocol (TDISP). This
protocol definition builds upon Component Measurement and Authentication
(CMA), and link Integrity and Data Encryption (IDE). It adds support for
assigning devices (PCI physical or virtual function) to a confidential VM
such that the assigned device is enabled to access guest private memory
protected by technologies like Intel TDX, AMD SEV-SNP, RISCV COVE, or ARM
CCA.

The "TSM" (TEE Security Manager) is a concept in the TDISP specification
of an agent that mediates between a "DSM" (Device Security Manager) and
system software in both a VMM and a confidential VM. A VMM uses TSM ABIs
to setup link security and assign devices. A confidential VM uses TSM
ABIs to transition an assigned device into the TDISP "RUN" state and
validate its configuration. From a Linux perspective the TSM abstracts
many of the details of TDISP, IDE, and CMA. Some of those details leak
through at times, but for the most part TDISP is an internal
implementation detail of the TSM.

CONFIG_PCI_TSM adds an "authenticated" attribute and "tsm/" subdirectory
to pci-sysfs. Consider that the TSM driver may itself be a PCI driver.
Userspace can watch for the arrival of a "TSM" device,
/sys/class/tsm/tsm0/uevent KOBJ_CHANGE, to know when the PCI core has
initialized TSM services.

The operations that can be executed against a PCI device are split into
two mutually exclusive operation sets, "Link" and "Security" (struct
pci_tsm_{link,security}_ops). The "Link" operations manage physical link
security properties and communication with the device's Device Security
Manager firmware. These are the host side operations in TDISP. The
"Security" operations coordinate the security state of the assigned
virtual device (TDI). These are the guest side operations in TDISP.

Only "link" (Secure Session and physical Link Encryption) operations are
defined at this stage. There are placeholders for the device security
(Trusted Computing Base entry / exit) operations.

The locking allows for multiple devices to be executing commands
simultaneously, one outstanding command per-device and an rwsem
synchronizes the implementation relative to TSM registration/unregistration
events.

Thanks to Wu Hao for his work on an early draft of this support.

Pull pci updates from Bjorn Helgaas:
"Enumeration:

- Add PCI_FIND_NEXT_CAP() and PCI_FIND_NEXT_EXT_CAP() macros that
take config space accessor functions.

Implement pci_find_capability(), pci_find_ext_capability(), and
dwc, dwc endpoint, and cadence capability search interfaces with
them (Hans Zhang)

- Leave parent unit address 0 in 'interrupt-map' so that when we
build devicetree nodes to describe PCI functions that contain
multiple peripherals, we can build this property even when
interrupt controllers lack 'reg' properties (Lorenzo Pieralisi)

- Add a Xeon 6 quirk to disable Extended Tags and limit Max Read
Request Size to 128B to avoid a performance issue (Ilpo Järvinen)

- Add sysfs 'serial_number' file to expose the Device Serial Number
(Matthew Wood)

- Fix pci_acpi_preserve_config() memory leak (Nirmoy Das)

Resource management:

- Align m68k pcibios_enable_device() with other arches (Ilpo
Järvinen)

- Remove sparc pcibios_enable_device() implementations that don't do
anything beyond what pci_enable_resources() does (Ilpo Järvinen)

- Remove mips pcibios_enable_resources() and use
pci_enable_resources() instead (Ilpo Järvinen)

- Clean up bridge window sizing and assignment (Ilpo Järvinen),
including:

- Leave non-claimed bridge windows disabled

- Enable bridges even if a window wasn't assigned because not all
windows are required by downstream devices

- Preserve bridge window type when releasing the resource, since
the type is needed for reassignment

- Consolidate selection of bridge windows into two new
interfaces, pbus_select_window() and
pbus_select_window_for_type(), so this is done consistently

- Compute bridge window start and end earlier to avoid logging
stale information

MSI:

- Add quirk to disable MSI on RDC PCI to PCIe bridges (Marcos Del Sol
Vives)

Error handling:

- Align AER with EEH by allowing drivers to request a Bus Reset on
Non-Fatal Errors (in addition to the reset on Fatal Errors that we
already do) (Lukas Wunner)

- If error recovery fails, emit FAILED_RECOVERY uevents for the
devices, not for the bridge leading to them.

This makes them correspond to BEGIN_RECOVERY uevents (Lukas Wunner)

- Align AER with EEH by calling err_handler.error_detected()
callbacks to notify drivers if error recovery fails (Lukas Wunner)

- Align AER with EEH by restoring device error_state to
pci_channel_io_normal before the err_handler.slot_reset() callback.

This is earlier than before the err_handler.resume() callback
(Lukas Wunner)

- Emit a BEGIN_RECOVERY uevent when driver's
err_handler.error_detected() requests a reset, as well as when it
says recovery is complete or can be done without a reset (Niklas
Schnelle)

- Align s390 with AER and EEH by emitting uevents during error
recovery (Niklas Schnelle)

- Align EEH with AER and s390 by emitting BEGIN_RECOVERY,
SUCCESSFUL_RECOVERY, or FAILED_RECOVERY uevents depending on the
result of err_handler.error_detected() (Niklas Schnelle)

- Fix a NULL pointer dereference in aer_ratelimit() when ACPI GHES
error information identifies a device without an AER Capability
(Breno Leitao)

- Update error decoding and TLP Log printing for new errors in
current PCIe base spec (Lukas Wunner)

- Update error recovery documentation to match the current code
and use consistent nomenclature (Lukas Wunner)

ASPM:

- Enable all ClockPM and ASPM states for devicetree platforms, since
there's typically no firmware that enables ASPM

This is a risky change that may uncover hardware or configuration
defects at boot-time rather than when users enable ASPM via sysfs
later. Booting with "pcie_aspm=off" prevents this enabling
(Manivannan Sadhasivam)

- Remove the qcom code that enabled ASPM (Manivannan Sadhasivam)

Power management:

- If a device has already been disconnected, e.g., by a hotplug
removal, don't bother trying to resume it to D0 when detaching the
driver.

This avoids annoying "Unable to change power state from D3cold to
D0" messages (Mario Limonciello)

- Ensure devices are powered up before config reads for
'max_link_width', 'current_link_speed', 'current_link_width',
'secondary_bus_number', and 'subordinate_bus_number' sysfs files.

This prevents using invalid data (~0) in drivers or lspci and,
depending on how the PCIe controller reports errors, may avoid
error interrupts or crashes (Brian Norris)

Virtualization:

- Add rescan/remove locking when enabling/disabling SR-IOV, which
avoids list corruption on s390, where disabling SR-IOV also
generates hotplug events (Niklas Schnelle)

Peer-to-peer DMA:

- Free struct p2p_pgmap, not a member within it, in the
pci_p2pdma_add_resource() error path (Sungho Kim)

Endpoint framework:

- Document sysfs interface for BAR assignment of vNTB endpoint
functions (Jerome Brunet)

- Fix array underflow in endpoint BAR test case (Dan Carpenter)

- Skip endpoint IRQ test if the IRQ is out of range to avoid false
errors (Christian Bruel)

- Fix endpoint test case for controllers with fixed-size BARs smaller
than requested by the test (Marek Vasut)

- Restore inbound translation when disabling doorbell so the endpoint
doorbell test case can be run more than once (Niklas Cassel)

- Avoid a NULL pointer dereference when releasing DMA channels in
endpoint DMA test case (Shin'ichiro Kawasaki)

- Convert tegra194 interrupt number to MSI vector to fix endpoint
Kselftest MSI_TEST test case (Niklas Cassel)

- Reset tegra194 BARs when running in endpoint mode so the BAR tests
don't overwrite the ATU settings in BAR4 (Niklas Cassel)

- Handle errors in tegra194 BPMP transactions so we don't mistakenly
skip future PERST# assertion (Vidya Sagar)

AMD MDB PCIe controller driver:

- Update DT binding example to separate PERST# to a Root Port stanza
to make multiple Root Ports possible in the future (Sai Krishna
Musham)

- Add driver support for PERST# being described in a Root Port
stanza, falling back to the host bridge if not found there (Sai
Krishna Musham)

Freescale i.MX6 PCIe controller driver:

- Enable the 3.3V Vaux supply if available so devices can request
wakeup with either Beacon or WAKE# (Richard Zhu)

MediaTek PCIe Gen3 controller driver:

- Add optional sys clock ready time setting to avoid sys_clk_rdy
signal glitching in MT6991 and MT8196 (AngeloGioacchino Del Regno)

- Add DT binding and driver support for MT6991 and MT8196
(AngeloGioacchino Del Regno)

NVIDIA Tegra PCIe controller driver:

- When asserting PERST#, disable the controller instead of mistakenly
disabling the PLL twice (Nagarjuna Kristam)

- Convert struct tegra_msi mask_lock to raw spinlock to avoid a lock
nesting error (Marek Vasut)

Qualcomm PCIe controller driver:

- Select PCI Power Control Slot driver so slot voltage rails can be
turned on/off if described in Root Port devicetree node (Qiang Yu)

- Parse only PCI bridge child nodes in devicetree, skipping unrelated
nodes such as OPP (Operating Performance Points), which caused
probe failures (Krishna Chaitanya Chundru)

- Add 8.0 GT/s and 32.0 GT/s equalization settings (Ziyue Zhang)

- Consolidate Root Port 'phy' and 'reset' properties in struct
qcom_pcie_port, regardless of whether we got them from the Root
Port node or the host bridge node (Manivannan Sadhasivam)

- Fetch and map the ELBI register space in the DWC core rather than
in each driver individually (Krishna Chaitanya Chundru)

- Enable ECAM mechanism in DWC core by setting up iATU with 'CFG
Shift Feature' and use this in the qcom driver (Krishna Chaitanya
Chundru)

- Add SM8750 compatible to qcom,pcie-sm8550.yaml (Krishna Chaitanya
Chundru)

- Update qcom,pcie-x1e80100.yaml to allow fifth PCIe host on Qualcomm
Glymur, which is compatible with X1E80100 but doesn't have the
cnoc_sf_axi clock (Qiang Yu)

Renesas R-Car PCIe controller driver:

- Fix a typo that prevented correct PHY initialization (Marek Vasut)

- Add a missing 1ms delay after PWR reset assertion as required by
the V4H manual (Marek Vasut)

- Assure reset has completed before DBI access to avoid SError (Marek
Vasut)

- Fix inverted PHY initialization check, which sometimes led to
timeouts and failure to start the controller (Marek Vasut)

- Pass the correct IRQ domain to generic_handle_domain_irq() to fix a
regression when converting to msi_create_parent_irq_domain()
(Claudiu Beznea)

- Drop the spinlock protecting the PMSR register - it's no longer
required since pci_lock already serializes accesses (Marek Vasut)

- Convert struct rcar_msi mask_lock to raw spinlock to avoid a lock
nesting error (Marek Vasut)

SOPHGO PCIe controller driver:

- Check for existence of struct cdns_pcie.ops before using it to
allow Cadence drivers that don't need to supply ops (Chen Wang)

- Add DT binding and driver for the SOPHGO SG2042 PCIe controller
(Chen Wang)

STMicroelectronics STM32MP25 PCIe controller driver:

- Update pinctrl documentation of initial states and use in runtime
suspend/resume (Christian Bruel)

- Add pinctrl_pm_select_init_state() for use by stm32 driver, which
needs it during resume (Christian Bruel)

- Add devicetree bindings and drivers for the STMicroelectronics
STM32MP25 in host and endpoint modes (Christian Bruel)

Synopsys DesignWare PCIe controller driver:

- Add support for x16 in devicetree 'num-lanes' property (Konrad
Dybcio)

- Verify that if DT specifies a single IRQ for all eDMA channels, it
is named 'dma' (Niklas Cassel)
