Document the Synaptics TDDI (Touch/Display Integration) panel hardware.
Along with the MIPI-DSI panel, these devices also have an in-built LED
backlight device and a touchscreen, all packed together in a single chip.
Also, add compatibles for supported panels - TD4101 and TD4300. Both
have the '-panel' suffix so as to remove any ambiguity between the panel
and touchscreen chips.

Rework the current allOf: section such that all handling of
clocks/clock-names properties happens first, and all handling
of power-domains/power-domain-names happens second.
This allows the allOf section to limit various GPU models to
matching clocks count in the first half, and apply the same
for power-domains count in the second half, without conflating
the two limits together.
This makes addition of GPU models with different clocks and
power-domains count easier. No functional change intended.

Pull clk updates from Stephen Boyd:
"There's a bunch of patches here across drivers/clk/ to migrate drivers
to use struct clk_ops::determine_rate() instead of the round_rate()
one so that we can remove the round_rate clk_op entirely. Brian has
taken up that task which nobody else has wanted to do for close to a
decade. Thanks Brian!
This is all prerequisite work to get to the real task of improving the
clk rate setting process. Once we have determine_rate() used
everywhere, we'll be able to do things like chain the rate request
structs in linked lists to order the rate setting operations or add
more parameters without having to change every clk driver in
existence. It's also nice to not have multiple ways to do something
which just causes confusion for clk driver authors. Overall I'm glad
this is getting done.
Beyond this change we also have a tweak to the clk_lookup() function
in the core framework to use hashing on the clk name instead of a clk
tree walk with string comparisons. We _still_ rely on the clk name to
be unique, because historically we've used globally unique strings to
describe the clk tree topology. This tree walk becomes increasingly
slow as more clks are added to the system. Searching from the roots
for a duplicate is simple but pretty dumb and it wastes boot time so
we're using a hash table as an improvement. Ideally we wouldn't rely
on the strings to be unique at all, relegating them to simply debug
information, but that is future work that will likely require some
sort of Kconfig knob indicating strings aren't used for topology
description.
Outside of the core framework changes we have the usual new SoC
support and fixes to clk drivers for things that were discovered once
the clks were used by consumer drivers. Nothing in particular is
jumping out at me in the "misc" pile, except maybe the Amlogic driver
that has gone through a refactoring. That series got a fix from
testing in -next though so it seems likely that things have been
getting good test coverage for a couple weeks already"

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

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

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

- 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

- Fix inverted PHY initialization check, which sometimes led to

- 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)
TI J721E PCIe driver:
- Add MODULE_DEVICE_TABLE() so driver can be autoloaded (Siddharth
Vadapalli)
- Power controller off before configuring the glue layer so the
controller latches the correct values on power-on (Siddharth
Vadapalli)
TI Keystone PCIe controller driver:
- Use devm_request_irq() so 'ks-pcie-error-irq' is freed when driver
exits with error (Siddharth Vadapalli)
- Add Peripheral Virtualization Unit (PVU), which restricts DMA from
PCIe devices to specific regions of host memory, to the ti,am65
binding (Jan Kiszka)
Xilinx NWL PCIe controller driver:
- Clear bootloader E_ECAM_CONTROL before merging in the new driver
value to avoid writing invalid values (Jani Nurminen)"
