[PATCH v2 0/4] Add LTC2495 support

[Yusuf Alper Bilgin <y.alperbilgin@gmail.com>]

Hi All,

This is the v2 of the patch series to add support for the LTC2495 ADC to
the ltc2497 driver and to enable the internal temperature channel for
the LTC2495 and LTC2499.

Many thanks to Andy Shevchenko and Krzysztof Kozlowski for their
detailed and helpful reviews on v1. I believe I've addressed all
feedbacks in this version.

Best Regards,

Alper

Changes in v2:
  - Rewrote all commit messages to use the imperative mood.
  - Added a justification for the new compatible string to the device
    tree binding commit message.
  - Removed all unrelated whitespace and formatting changes.
  - Removed redundant explicit `false` initializers from structs.
  - Replaced the magic number for Kelvin conversion with a define.
  - Improved comments for defines and temperature scaling constants.
  - Renamed confusing macros and struct fields to be more descriptive.
  - Replaced dynamic channel allocation with a static array approach
    using a shared macro to improve readability.
  - Optimized data structure layouts based on pahole output to remove
    memory holes.

Implementation Notes
 - checkpatch warning: The new static array approach uses a shared macro
   for the common channels (`LTC2497_CHANNELS`), which triggers a
   checkpatch.pl warning: "Macros with complex values should be enclosed
   in parentheses". However, this will cause a compilitaion error, as an
   initializer list cannot be parenthesized.
 - uV to mV conversion: I could not find a standard macro, so a manual
   division is used for now. This could be a point of future
   improvement.
