Add "loongson,ls2k0300-rtc" dedicated compatible to represent the RTC
interface of the Loongson-2K0300 chip.
Its hardware design is similar to that of the Loongson-1B, but it does
not support the alarm feature.

The `interrupts` property indicates an RTC alarm interrupt, which is
required for RTCs that support the alarm feature, which is not supported
by the Loongson-1C RTC. We exclude it for a more accurate description.
Changing the `allowed` property is ABI-breaking behavior, but
throughout the existing Loongson DTS{i}, the description of the RTC
nodes conforms to the modified bingding rules.
Thus, the existing Loongson DTS{i} will not be affected.

Add two flags for KVM_CAP_X2APIC_API to allow userspace to control support
for Suppress EOI Broadcasts when using a split IRQCHIP (I/O APIC emulated
by userspace), which KVM completely mishandles. When x2APIC support was
first added, KVM incorrectly advertised and "enabled" Suppress EOI
Broadcast, without fully supporting the I/O APIC side of the equation,
i.e. without adding directed EOI to KVM's in-kernel I/O APIC.
That flaw was carried over to split IRQCHIP support, i.e. KVM advertised
support for Suppress EOI Broadcasts irrespective of whether or not the
userspace I/O APIC implementation supported directed EOIs. Even worse,
KVM didn't actually suppress EOI broadcasts, i.e. userspace VMMs without
support for directed EOI came to rely on the "spurious" broadcasts.
KVM "fixed" the in-kernel I/O APIC implementation by completely disabling
support for Suppress EOI Broadcasts in commit 0bcc3fb95b97 ("KVM: lapic:
stop advertising DIRECTED_EOI when in-kernel IOAPIC is in use"), but
didn't do anything to remedy userspace I/O APIC implementations.
KVM's bogus handling of Suppress EOI Broadcast is problematic when the
guest relies on interrupts being masked in the I/O APIC until well after
the initial local APIC EOI. E.g. Windows with Credential Guard enabled
handles interrupts in the following order:
1. Interrupt for L2 arrives.
2. L1 APIC EOIs the interrupt.
3. L1 resumes L2 and injects the interrupt.
4. L2 EOIs after servicing.
5. L1 performs the I/O APIC EOI.
Because KVM EOIs the I/O APIC at step #2, the guest can get an interrupt
storm, e.g. if the IRQ line is still asserted and userspace reacts to the
EOI by re-injecting the IRQ, because the guest doesn't de-assert the line
until step #4, and doesn't expect the interrupt to be re-enabled until
step #5.
Unfortunately, simply "fixing" the bug isn't an option, as KVM has no way
of knowing if the userspace I/O APIC supports directed EOIs, i.e.
suppressing EOI broadcasts would result in interrupts being stuck masked
in the userspace I/O APIC due to step #5 being ignored by userspace. And
fully disabling support for Suppress EOI Broadcast is also undesirable, as
picking up the fix would require a guest reboot, *and* more importantly
would change the virtual CPU model exposed to the guest without any buy-in
from userspace.
Add KVM_X2APIC_ENABLE_SUPPRESS_EOI_BROADCAST and
KVM_X2APIC_DISABLE_SUPPRESS_EOI_BROADCAST flags to allow userspace to
explicitly enable or disable support for Suppress EOI Broadcasts. This
gives userspace control over the virtual CPU model exposed to the guest,
as KVM should never have enabled support for Suppress EOI Broadcast without
userspace opt-in. Not setting either flag will result in legacy quirky
behavior for backward compatibility.
Disallow fully enabling SUPPRESS_EOI_BROADCAST when using an in-kernel
I/O APIC, as KVM's history/support is just as tragic. E.g. it's not clear
that commit c806a6ad35bf ("KVM: x86: call irq notifiers with directed EOI")
was entirely correct, i.e. it may have simply papered over the lack of
Directed EOI emulation in the I/O APIC.
Note, Suppress EOI Broadcasts is defined only in Intel's SDM, not in AMD's
APM. But the bit is writable on some AMD CPUs, e.g. Turin, and KVM's ABI
is to support Directed EOI (KVM's name) irrespective of guest CPU vendor.

For all SoCFPGA platforms, whether it has the "intel" or "altr" vendor
prefix are referring to the same business unit that is responsible for
the platform. And now that Altera has spun off to be a separate corporate
entity from Intel, it would make sense to have the device bindings
documentation in the same file.
Move the Intel AgileX board binding documentations into the same file that

The firmware-name property was originally introduced to allow end-users
and integrators to select use-case-specific firmware for the WCN6855.
However, specifying firmware for an M.2 WLAN module in the Device Tree
is not appropriate. Instead, this functionality will be handled within
the ath11k driver. Therefore, the firmware-name property is now

Currently, the dpll subsystem exports the fractional frequency offset
(FFO) in parts per million (ppm). This granularity is insufficient for
high-precision synchronization scenarios which often require parts per
trillion (ppt) resolution.
Add a new netlink attribute DPLL_A_PIN_FRACTIONAL_FREQUENCY_OFFSET_PPT
to expose the FFO in ppt.
Update the dpll netlink core to expect the driver-provided FFO value
to be in ppt. To maintain backward compatibility with existing userspace
tools, populate the legacy DPLL_A_PIN_FRACTIONAL_FREQUENCY_OFFSET
attribute by dividing the new ppt value by 1,000,000.
Update the zl3073x and mlx5 drivers to provide the FFO value in ppt:
- zl3073x: adjust the fixed-point calculation to produce ppt (10^12)
instead of ppm (10^6).
- mlx5: scale the existing ppm value by 1,000,000.

The current documentation implies that pci_epc_set_bar() is only used
before the host enumerates the endpoint.
In practice, some Endpoint Controllers support calling pci_epc_set_bar()
multiple times for the same BAR (without clearing it) in order to update
inbound address translations after the host has programmed the BAR base
address, which some Endpoint Functions such as vNTB already rely on.
Add document text for that.
Also document the expected call flow for BAR subrange mapping
(pci_epf_bar.num_submap / pci_epf_bar.submap), which may require a
second pci_epc_set_bar() call after the host has programmed the BAR base
address.

One big Qualcomm Bluetooth schema is hardly manageable: it lists all
possible properties (19 supplies). Split qcom,wcn6750-bt to separate
bindings, so device schema will be easier to read/maintain and list only
relevant properties.

One big Qualcomm Bluetooth schema is hardly manageable: it lists all
possible properties (19 supplies). Split qcom,wcn3990-bt to separate
bindings, so device schema will be easier to read/maintain and list only
relevant properties.
This binding is very similar to qcom,wcn3950-bt, however devices have
additional VDD_CH1 supply.

One big Qualcomm Bluetooth schema is hardly manageable: it lists all
possible properties (19 supplies). Split qcom,qca9377-bt to separate
bindings, so device schema will be easier to read/maintain and list only

Existing binding has incomplete and incorrect list of supplies (e.g.
there is no VDD_XO) and Linux driver does not ask for any, thus keep
this state unchanged.

One big Qualcomm Bluetooth schema is hardly manageable: it lists all
possible properties (19 supplies). Split common part and
qcom,qca2066-bt to separate bindings, so each schema will be easier to
read/maintain and list only relevant properties.
The existing bindings do not mention interrupts, but
am335x-sancloud-bbe-extended-wifi.dts already defines such. This issue
is not being fixed here.
Existing binding also did not mention any supplies (which do exist as
confirmed in datasheet) and Linux driver does not ask for any, thus keep
this state unchanged.

'calibrate' was a one-shot event sent to the sensor to calibrate itself.
It is used on Bosch sensors (BMI160, BMA254).
Light sensors work differently: They are first put in calibration mode,
tests are run to collect information and calculate the calibration
values to apply. Once done, the sensors are put back in normal mode.
Accept boolean true and false (not just true) to enter/exit calibration
state.
Check "echo 0 > calibrate" is supported.

fs-verity introduced inode flag for inodes with enabled fs-verity on
them. This patch adds FS_XFLAG_VERITY file attribute which can be
retrieved with FS_IOC_FSGETXATTR ioctl() and file_getattr() syscall.
This flag is read-only and can not be set with corresponding set ioctl()
and file_setattr(). The FS_IOC_SETFLAGS requires file to be opened for
writing which is not allowed for verity files. The FS_IOC_FSSETXATTR and
file_setattr() clears this flag from the user input.
As this is now common flag for both flag interfaces (flags/xflags) add
it to overlapping flags list to exclude it from overwrite.

The language definition was extracted from the new
draft-ietf-nfsv4-posix-acls specification. This ensures good
constant and type name alignment between the spec and the Linux

We've run out of bits to describe RISC-V ISA extensions in our initial
hwprobe key, RISCV_HWPROBE_KEY_IMA_EXT_0. So, let's add
RISCV_HWPROBE_KEY_IMA_EXT_1, along with the framework to set the
appropriate hwprobe tuple, and add testing for it.
Based on a suggestion from Andrew Jones <andrew.jones@oss.qualcomm.com>,
also fix the documentation for RISCV_HWPROBE_KEY_IMA_EXT_0.
