Convert the in_voltage_scale_available and in_voltage_offset_available
attributes from legacy IIO_DEVICE_ATTR with custom show functions to the
IIO framework's read_avail callback. This uses the framework's built-in
support for _available attributes, removing the need for manual sysfs
formatting.
Precompute the available scale values at probe time since they depend on
the reference voltage which does not change after initialization.

Improve the ltc2309_chip_info structure with better type safety and
memory efficiency:
- Add __counted_by_ptr() annotation to the channels pointer, linking
it to num_channels for improved bounds checking and kernel hardening
- Reorder structure fields to minimize padding:
* Place read_delay_us before num_channels
* This reduces struct size and eliminates internal gaps
- Reorder field initialization to match the structure definition order
The __counted_by_ptr() attribute enables compile-time and runtime
verification that array accesses to channels[] stay within the bounds
specified by num_channels, improving memory safety.

The LTC2305 requires a minimum 1.6μs delay between the I2C write
operation (channel selection) and the subsequent read operation to
allow the chip to process the command and prepare the result. While
not explicitly documented in the datasheet, this timing requirement
was identified by the hardware designer as necessary for reliable
operation.
Add a read_delay_us field to both the ltc2309_chip_info and ltc2309
device structures to support chip-specific timing requirements. Use
fsleep() to implement the delay when non-zero, with LTC2305 set to
2μs (1.6μs requirement rounded up). LTC2309 does not require
additional delay beyond inherent I2C bus timing.
This extends the existing LTC2305 support added in
(commit 8625d418d24b ("iio: adc: ltc2309: add support for ltc2305"))
with the missing inter-transaction delay.

Some IMU chips in the LSM6DSX family have sensor fusion features that
combine data from the accelerometer and gyroscope. One of these features
generates rotation vector data and makes it available in the hardware
FIFO as a quaternion (more specifically, the X, Y and Z components of the
quaternion vector, expressed as 16-bit half-precision floating-point
numbers).
Add support for a new sensor instance that allows receiving sensor fusion
data, by defining a new struct st_lsm6dsx_fusion_settings (which contains
chip-specific details for the sensor fusion functionality), and adding this
struct as a new field in struct st_lsm6dsx_settings. In st_lsm6dsx_core.c,
populate this new struct for the LSM6DSV and LSM6DSV16X chips, and add the
logic to initialize an additional IIO device if this struct is populated
for the hardware type being probed.
Note: a new IIO device is being defined (as opposed to adding channels to
an existing device) because the rate at which sensor fusion data is
generated may not match the data rate from any of the existing devices.
Tested on LSM6DSV16X.

The DRDY_MASK feature implemented in sensor chips marks gyroscope and
accelerometer invalid samples (i.e. samples that have been acquired during
the settling time of sensor filters) with the special values 0x7FFFh,
0x7FFE, and 0x7FFD.
The driver checks FIFO samples against these special values in order to
discard invalid samples; however, it does the check regardless of the type
of samples being processed, whereas this feature is specific to gyroscope
and accelerometer data. This could cause valid samples to be discarded.
Fix the above check so that it takes into account the type of samples being
processed. To avoid casting to __le16 * when checking sample values, clean
up the type representation for data read from the FIFO.

Move the scan buf.chans array into a union along with a struct that
gives the layout of the buffer with all channels enabled.
Although not technically required in this case, if there had been a
different number of items before the quaternion, there could have been
a subtle bug with the special alignment needed for the quaternion
channel data and the array would have been too small.

Fix timestamp alignment when a scan buffer contains an element larger
than sizeof(int64_t). Currently s32 quaternions are the only such
element, and the one driver that has this (hid-sensor-rotation) has a
workaround in place already so this change does not affect it.
Previously, we assumed that the timestamp would always be 8-byte aligned
relative to the end of the scan buffer, but in the case of a scan buffer
a 16-byte quaternion vector, scan_bytes == 32, but the timestamp needs
to be placed at offset 16, not 24.
ts_offset is now a value in bytes so we have to change how the array
access is done.

Use roundup_pow_of_two() in the calculation of iio_storage_bytes_for_si()
when scan_type->repeat > 1 to ensure that the size is a power of two.
storagebits is always going to be a power of two bytes, so we only need
to apply this to the repeat factor. The storage size is also used for
alignment, and we want to ensure that all alignments are a power of two.
The only repeat in use in the kernel currently is for quaternions, which
have a repeat of 4, so this does not change the result for existing
users.

Change the drm_err to drm_dbg_kms when we fail to read the FEC
capability. This is mainly because this is called from intel_dp_detect.
Which ends up in race more frequently in case of MST scenarios,
when we are disabling streams but the downstream Dock still sends
signals which causes intel_dp_detect to be invoked which has DPCD
reads. These pass until the Transcoder and DPLL go down causing
AUX to go down too. At this point AUX Timeouts are expected and not
an issue. But this drm_err gets flagged in CI causing noise even
for passing scenarios.

The qcom pinctrl core supports marking functions that represent GPIO mode
via PINCTRL_GPIO_PINFUNCTION(), so that strict pinmuxing does not reject
GPIO requests for pins that are muxed to the GPIO function.
ipq4019 still describes its gpio function with QCA_PIN_FUNCTION(gpio),
so it is not treated as a GPIO pin function. As a result, GPIO consumers
can still conflict with pinctrl states that select the "gpio" function.
Add a QCA_GPIO_PIN_FUNCTION() helper and use it for the ipq4019 gpio
function, matching how the msm-based qcom drivers handle this.

KVM selftests type renames for 7.1
Renames types across all KVM selftests to more closely align with types used
in the kernel:
vm_vaddr_t -> gva_t
vm_paddr_t -> gpa_t
uint64_t -> u64
uint32_t -> u32
uint16_t -> u16
uint8_t -> u8
int64_t -> s64
int32_t -> s32
int16_t -> s16
int8_t -> s8
Using the kernel's preferred types eliminates a source of friction for many
contributors, as the majority of KVM selftests contributions come from kernel
developers. The kernel names are also shorter, which allows for more concise
code, and in any many cases eliminates newlines thanks to shorter types and
parameter names.
Rename variables and parameters as well as types, e.g. gpa instead of paddr,
to again align with the kernel, and in a few cases to remove ambiguity, e.g.
where paddr is used to refer to a _host_ physical address.
