Ammar MustafaandJonathan Cameron d2a4ec19d2 Docs: iio: ad7191 Correct clock configuration
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.

Taha Ed-DafiliandJonathan Cameron d6bd0e2745 docs: iio: adxl345: update event attributes and scaling math
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.

Taha Ed-DafiliandJonathan Cameron a1fe33e07b docs: iio: adxl345: grammar and formatting cleanups
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.
