Convert the Mikrotik RouterBoard RB532 to use GPIO descriptors
by defining a software node for the GPIO chip, then register
the button platform device with full info passing the GPIO
as a device property.
This can be used as a base to move more of the RB532 devices
over to passing GPIOs using device properties.
Use the GPIO_ACTIVE_LOW flag and drop the inversion in the
rb532_button_pressed() function.

Declare the PLLs and fixed factors found in the EyeQ6Lplus OLB as part
of the match data for the "mobileye,eyeq6lplus-olb" compatible.
The PLL and fixed factor of the CPU are registered in early init as they
are required during the boot by the GIC timer.
Also select clk-eyeq for all EYEQ SoCs instead of listing each one
individually, as it is needed by all Mobileye EyeQ SoC.

The spread spectrum of the PLL found in eyeQ OLB is in 1/1024 parts of the
frequency, not in 1/1000, so adjust the computation of the accuracy. Also
correct the downspreading to match.

The output of the PLL is routed before the post-divisor so it should be
ignored when computing the frequency of the PLL, functional change is
implemented to reflect how the clock signal is wired internally.
For the PLL of the EyeQ5, EyeQ6L, and EyeQ6H, this change has no impact
as the post-divisor is either reported as disabled or set to 1. The PLL
frequency is the same before and after the post-divisor.
For the PLL in EyeQ6Lplus, however, the post-divisor is not 1, so it must
be ignored to compute the correct frequency.

Add the match data for the pinctrl found in the EyeQ6Lplus OLB. The pin
control is identical in function to the one present in the EyeQ5 but

Instead of using the pin descriptions, pin functions and register offsets
of the EyeQ5 directly, access those via a pointer to a newly introduced
struct eq5p_match_data.
This structure contains, in addition to the pin descriptions and pin
functions, an array of pin banks. Each bank holds the number of pins
and the register offsets.
All functions accessing a pin now use a pointer to a bank structure and
an offset inside that bank. The conversion from a pin number to a bank
and an offset is done in the new function eq5p_pin_to_bank_offset(),
which replace eq5p_pin_to_bank() and eq5p_pin_to_offset().
All the data related to the EyeQ5 is declared with the eq5p_eyeq5_
prefix to distinguish it from the common code.
During the probe, we use the parent OF node to get the match data.
We cannot directly use an OF node since pinctrl-eyeq5 is an auxiliary
device of clk-eyeq.

Declare the two reset domains found in the EyeQ6Lplus OLB and add
them to the data matched by 'mobileye,eyeq6lplus-olb' compatible.
Those reset domains are identical to those present in the EyeQ5
OLB, so no changes are needed to support them.
Also select reset-eyeq for all EYEQ SoCs instead of listing each one
individually, as it is needed by all Mobileye EyeQ SoC.

When a Bluetooth controller encounters a coredump, it triggers the
Subsystem Restart (SSR) mechanism. The controller first reports the
coredump data and, once the upload is complete, sends a hw_error
event. The host relies on this event to proceed with subsequent
recovery actions.
If the host has not finished processing the coredump data when the
hw_error event is received, it waits until either the processing is
complete or the 8-second timeout expires before handling the event.
The current implementation clears QCA_MEMDUMP_COLLECTION using
clear_bit(), which does not wake up waiters sleeping in
wait_on_bit_timeout(). As a result, the waiting thread may remain
blocked until the timeout expires even if the coredump collection
has already completed.
Fix this by clearing QCA_MEMDUMP_COLLECTION with
clear_and_wake_up_bit(), which also wakes up the waiting thread and
allows the hw_error handling to proceed immediately.
Test case:
- Trigger a controller coredump using:
hcitool cmd 0x3f 0c 26
- Tested on QCA6390.
- Capture HCI logs using btmon.
- Verify that the delay between receiving the hw_error event and
initiating the power-off sequence is reduced compared to the
timeout-based behavior.

TI WL183x controllers advertise support for the HCI Enhanced Setup

legacy HCI Setup Synchronous Connection (0x0028).

Some MT6639 Bluetooth USB interfaces (e.g. IMC Networks 13d3:3588 on
ASUS ROG STRIX X870E-E and ProArt X870E-Creator boards) expose only a
single alternate setting (alt 0) on the ISO interface. The driver
unconditionally requests alt setting 1, which fails with EINVAL on
these devices, causing a ~20 second initialization delay and no LE
audio support.
Check the number of available alternate settings before selecting one.
If only alt 0 exists, use it; otherwise request alt 1 as before.

The MediaTek MT7927 (Filogic 380) combo WiFi 7 + BT 5.4 module uses
hardware variant 0x6639 for its Bluetooth subsystem. Without this patch,
the chip fails with "Unsupported hardware variant (00006639)" or hangs
during firmware download.
Three changes are needed to support MT6639:
1. CHIPID workaround: On some boards the BT USB MMIO register reads
0x0000 for dev_id, causing the driver to skip the 0x6639 init path.
Force dev_id to 0x6639 only when the USB VID/PID matches a known
MT6639 device, avoiding misdetection if a future chip also reads
zero. This follows the WiFi-side pattern that uses PCI device IDs
to scope the same workaround.
2. Firmware naming: MT6639 uses firmware version prefix "2_1" instead of
"1_1" used by MT7925 and other variants. The firmware path is
mediatek/mt7927/BT_RAM_CODE_MT6639_2_1_hdr.bin, using the mt7927
directory to match the WiFi firmware convention. The filename will
likely change to use MT7927 once MediaTek submits a dedicated
Linux firmware binary.
3. Section filtering: The MT6639 firmware binary contains 9 sections, but
only sections with (dlmodecrctype & 0xff) == 0x01 are Bluetooth-related.
Sending the remaining WiFi/other sections causes an irreversible BT
subsystem hang requiring a full power cycle. This matches the Windows
driver behavior observed via USB captures.
Also add 0x6639 to the reset register (CONNV3) and firmware setup switch

When hci_register_dev() fails in hci_uart_register_dev()
HCI_UART_PROTO_INIT is not cleared before calling hu->proto->close(hu)
and setting hu->hdev to NULL. This means incoming UART data will reach
the protocol-specific recv handler in hci_uart_tty_receive() after
resources are freed.
Clear HCI_UART_PROTO_INIT with a write lock before calling
hu->proto->close() and setting hu->hdev to NULL. The write lock ensures
all active readers have completed and no new reader can enter the
protocol recv path before resources are freed.
This allows the protocol-specific recv functions to remove the
"HCI_UART_REGISTERED" guard without risking a null pointer dereference
if hci_register_dev() fails.

On platforms using an M.2 slot with both UART and USB support, bt_en is
pulled high by hardware. In this case, software-based power control
should be disabled. The current platforms are Lemans-EVK and Monaco-EVK.
Add QCA_WCN7850 to the existing condition so that power_ctrl_enabled is

Add a new driver for the 'virt-ctrl' device found on QEMU virt machines
(e.g. m68k). This device provides a simple interface for system reset
and power off [1].
This driver utilizes the modern system-off API to register callbacks
for both system restart and power off. It also registers a reboot
notifier to catch SYS_HALT events, ensuring that LINUX_REBOOT_CMD_HALT
is properly handled. It is designed to be generic and can be reused by
other architectures utilizing this QEMU device.

KVM/arm64 updates for 7.1
* New features:
- Add support for tracing in the standalone EL2 hypervisor code,
which should help both debugging and performance analysis.
This comes with a full infrastructure for 'remote' trace buffers
that can be exposed by non-kernel entities such as firmware.
- Add support for GICv5 Per Processor Interrupts (PPIs), as the
starting point for supporting the new GIC architecture in KVM.
- Finally add support for pKVM protected guests, with anonymous
memory being used as a backing store. About time!
* Improvements and bug fixes:
- Rework the dreaded user_mem_abort() function to make it more
maintainable, reducing the amount of state being exposed to
the various helpers and rendering a substantial amount of
state immutable.
- Expand the Stage-2 page table dumper to support NV shadow
page tables on a per-VM basis.
- Tidy up the pKVM PSCI proxy code to be slightly less hard
to follow.
- Fix both SPE and TRBE in non-VHE configurations so that they
do not generate spurious, out of context table walks that
ultimately lead to very bad HW lockups.
- A small set of patches fixing the Stage-2 MMU freeing in error
cases.
- Tighten-up accepted SMC immediate value to be only #0 for host
SMCCC calls.
- The usual cleanups and other selftest churn.

s32ton() shifts by n-1 where n is the field's report_size, a value that
comes directly from a HID device. The HID parser bounds report_size
only to <= 256, so a broken HID device can supply a report descriptor
with a wide field that triggers shift exponents up to 256 on a 32-bit
type when an output report is built via hid_output_field() or
hid_set_field().
Commit ec61b41918587 ("HID: core: fix shift-out-of-bounds in
hid_report_raw_event") added the same n > 32 clamp to the function
snto32(), but s32ton() was never given the same fix as I guess syzbot
hadn't figured out how to fuzz a device the same way.
Fix this up by just clamping the max value of n, just like snto32()
does.

The PPE enforces output frame size limits via per-tag-layer VLAN_MTU
registers that the driver never initializes. The hardware defaults do
not account for PPPoE overhead, causing the PPE to punt encapsulated
frames back to the CPU instead of forwarding them.
Initialize the registers at PPE start and on MTU changes using the
maximum GMAC MTU. This is a conservative approximation -- the actual
per-PPE requirement depends on egress path, but using the global
maximum ensures the limits are never too small.

The do-while poll loop uses jiffies for its timeout:
expires = jiffies + msecs_to_jiffies(10);
jiffies is sampled at an arbitrary point within the current tick, so the
first partial tick contributes anywhere from a full tick down to nearly
zero real time. For small msecs_to_jiffies() results this is
significant, the effective poll window can be much shorter than the
requested 10ms, and in the worst case the loop exits after a single
iteration (e.g., when HZ=100), well before the device has delivered the
CQE.
Replace the loop with read_poll_timeout_atomic(), which counts elapsed
time via udelay() accounting rather than jiffies, guaranteeing the full
poll window regardless of HZ.
Additionally, read_poll_timeout_atomic() executes the poll operation one
more time after the timeout has expired, giving the CQE a final chance
to be detected. The old do-while loop could exit without a final poll if
the timeout expired during the udelay() between iterations.

mlx5e_fix_features() returns early when the netdevice is not present.
This is correct during profile transitions where priv is cleared, but it
also incorrectly blocks feature fixups during register_netdev(), when
the device is also not yet present.
It is not trivial to distinguish between both cases as we cannot use
priv to carry state, and in both cases reg_state == NETREG_REGISTERED.
Force a netdev features update after register_netdev() completes, where
the device is present and fix_features() can actually work.
This is not a pretty solution, as it results in an additional features
update call (register_netdevice() already calls
__netdev_update_features() internally), but it is the simplest,
cleanest, and most robust way I found to fix this issue after multiple
attempts.
This fixes an issue on systems where CQE compression is enabled by
default, RXHASH remains enabled after registration despite the two
features being mutually exclusive.

MDIO bus controllers are not required to wait for write transactions to
complete before returning as synchronization is often achieved by polling
status bits.
This can cause issues when disabling interrupts since an interrupt could
fire before the interrupt handler is unregistered and there's no status
bit to poll.
Add a phy_write_barrier() function and use it in phy_disable_interrupts()
to fix this issue. The write barrier just reads an MII register and
discards the value, which is enough to guarantee that previous writes have
completed.

This adds an MDIO driver for PIC64-HPSC/HX. The hardware supports C22
and C45 but only C22 is implemented in this commit.
This MDIO hardware is based on a Microsemi design supported in Linux by
mdio-mscc-miim.c. However, The register interface is completely
different with pic64hpsc, hence the need for a separate driver.
The documentation recommends an input clock of 156.25MHz and a prescaler
of 39, which yields an MDIO clock of 1.95MHz.
The hardware supports an interrupt pin or a "TRIGGER" bit that can be
polled to signal transaction completion. This commit uses polling.
This was tested on Microchip HB1301 evalkit with a VSC8574 and a
VSC8541.
