Update the documentation to reflect the recent driver additions for
event scaling and the double tap threshold value, alongside correcting
existing technical errors in scale calculations.
Key changes:
- Fix the 62.5 g/LSB typo to 62.5 mg/LSB and add SI unit conversion.
- Correct decimal precision of in_accel_scale and
in_accel_scale_available to match the actual SI unit (m/s^2)
values reported by the driver.
- Document the newly generated event scale attributes in the ABI table
(e.g., in_accel_mag_rising_scale, in_accel_gesture_singletap_scale).
- Document the newly exposed in_accel_gesture_doubletap_value attribute.
- Add a sysfs example showing how to read and interpret the newly
implemented event scale factor.

Correct several grammatical errors, typos, and pluralization issues
throughout the ADXL345 documentation.
Key changes include:
- Changing 'generic' to 'general-purpose'
- Correcting 'axis' to 'axes' in multiple tables and descriptions
- Improving phrasing in the device attributes section
- Fixing 'latent' to 'latency' in usage examples
- Sorting the existing event attribute table alphabetically for
better readability and to establish a clean baseline for future
additions.

Add UFS Host Controller (UFSHC) compatible for x1e80100 SoC. Use SM8550
as a fallback since x1e80100 is fully compatible with it.
Qualcomm UFSHC is no longer compatible with JEDEC UFS-2.0 binding.
Avoid using the "jedec,ufs-2.0" string in the compatible property.

Add support for specifying OPPs for the Qualcomm Inline Crypto Engine
by allowing the use of the standard "operating-points-v2" property in
the ICE device node.
ICE clock management was handled by the storage drivers in legacy
bindings, so the ICE driver itself had no mechanism for clock scaling.
With the introduction of the new standalone ICE device node, clock
control must now be performed directly by the ICE driver. Enabling
operating-points-v2 allows the driver to describe and manage the
frequency and voltage requirements for proper DVFS operation.

The ACPI spec states that the operating system should respond
to a fatal ACPI error by "performing a controlled OS shutdown in
a timely fashion". Comply with the ACPI specification by powering
off the system when ACPICA signals a fatal ACPI error. Users can
still disable this behavior by using the acpi.poweroff_on_fatal
kernel option to work around firmware bugs.

In a typical system using the Samsung S2MPG10 PMIC, an S2MPG11 is used
as a sub-PMIC.
The interface for both is the ACPM firmware protocol, so update the
binding to allow the relevant node and update the example here to
describe the connection for both PMICs.
Since we have two PMICs here, but can not use the 'reg' property (as
the addressing is based on software, i.e. the ACPM firmware), the node
names reflect that with their respective suffix. The existing 'pmic'
therefore becomes deprecated in favour of 'pmic-1'.
While at it, update the example.

Add compatible string fsl,imx25-nand and fsl,imx27-nand (over 15 years
chips). Add one optional clocks for it because i.MX25 and i.MX27 upstream
DTS defines them.

The AMD QSPI controller supports an advanced connection modes called
Stacked mode which allow the controller to treat two different flashes
as one storage.
In Stacked connection mode flashes share the same SPI bus, but different CS
line, controller driver asserts the CS of the flash to which it needs to
communicate. Stacked mode is a software abstraction rather than a
controller feature or capability. At any given time, the controller
communicates with one of the two connected flash devices, as determined by
the requested address and data length. If an operation starts on one flash
and ends on the other, the mtd layer needs to split it into two separate
operations and adjust the data length accordingly. For more information on
the modes please feel free to go through the controller flash interface
below [1].
To support stacked mode, the existing MTD concat driver has been extended
to be more generic, enabling multiple sets of MTD partitions to be
virtually concatenated, with each set forming a distinct logical MTD
device.
A new Device Tree property is introduced to facilitate this, containing
phandles of the partitions to be concatenated with the one where the
property is defined. This approach supports multiple sets of concatenated
partitions.

The Synopsys DesignWare AXI DMA Controller on Agilex5, the controller
operates on a cache-coherent AXI interface, where DMA transactions are
automatically kept coherent with the CPU caches. In previous generations
SoC (Stratix10 and Agilex) the interconnect was non-coherent, hence there
is no need for dma-coherent property to be presence. In Agilex 5, the
architecture has changed. It introduced a coherent interconnect that
supports cache-coherent DMA.
