The Y-axis calibbias rows in adxl345.rst, adxl313.rst and adxl380.rst
use a different wording than the matching X-axis and Z-axis rows in
the same tables: the X/Z rows say "Calibration offset for the
X/Z-axis accelerometer channel." while the Y row says "Y-axis (or
y-axis) acceleration offset correction".
Make the Y-axis row match the other two so each driver's sysfs
table has consistent capitalisation and wording.

In the data storage description of a scan element, the first character
after the colon can have the values 's' and 'u' to specify signed and
unsigned integers, respectively.
Add 'f' as an allowed value to specify floating-point numbers formatted
according to the IEEE 754 standard.

Correct the ad7191 documentation to match the datasheet:
- Fix inverted CLKSEL pin logic: device uses external clock when pin is
inactive, and internal CMOS/crystal when high.
- Correct CMOS-compatible clock pin from MCLK2 to MCLK1.

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.

ADC inputs can be classified into a few different types according to how
they measure the input signal, how restrained the signal is, and number of
input pins. Even though datasheets tend to provide many details about their
inputs and measurement procedures, it may not always be clear how to model
those inputs into IIO channels.
For example, some differential ADCs can have their inputs configured into
pseudo-differential channels. In that configuration, only one input
connects to the signal of interest as opposed to using two inputs of a
differential input configuration. Datasheets sometimes also refer to
pseudo-differential inputs as single-ended inputs even though they have
distinct physical configuration and measurement procedure.
Document consolidated ADC input types and how they are usually described
and supported in device tree and IIO, respectively.

Add datasheet links for adis16486, adis16487 and adis16489
Six Degrees of Freedom Inertial Sensors into the existing
adis16480 driver documentation.
adis16486 is similar to adis16485, has the exact same channels
but acceleration and delta velocity scales are different.
adis16487 is fallback compatible with adis16485.
adis16489 is similar to adis16488 but lacks the magnetometer
and has a different accelerometer scale.
