LLM review

This series adds the EVAL-LTPA-LNAKIT reference design page (a new add-on
kit for the EVAL-LTPA-KIT / LTpowerAnalyzer™).

Session: 35968045296

e930794 - Add EVAL-LTPA-LNAKIT documentation

Dangling figure reference: line 81 hardcodes "Figure 8 illustrates the
basic hardware setup...", but with numfig enabled the referenced figure
(hw-setup-noise) is actually Figure 6 on this page (5 figures precede it:
the hero image + the 4-image gain-profile grid). This text looks copied
from the original source with the wrong figure number. Replaced with a
:numref: reference to a named figure so it can't drift again.

Broken :ez: role target: :ez:`EngineerZone Support Community <ez/reference-designs>` resolves to
https://ez.analog.com/ez/reference-designs — the ez segment is doubled,
since the role already prefixes https://ez.analog.com. Fixed to
<reference-designs>, matching the dominant convention elsewhere in
docs/solutions/reference-designs/*. Note the same wrong pattern already
exists in eval-ltpa-kit/index.rst and a few other pages predating this
PR — out of scope here but worth a follow-up cleanup.

Typos: freqeuncies -> frequencies, and LNAmplifier Controls ->
LNA Controls (the rest of the page consistently says "LNA").

Also cleaned up trailing whitespace and a stray double space introduced by
the new page.

CI warnings

The vale failures for LNAmplifier and freqeuncies are real typos,
fixed by the attached patch. The pcs failure is a false positive
(abbreviation for "pieces"), left as-is.

The 5x "Cannot scale image!" / "Could not obtain image size" Sphinx
warnings were reproduced locally: git lfs pull fetches valid PNGs and the
page builds without warnings. Re-writing the same 5 images (the hero image
and the 4 grid gain-profile images) back to their raw LFS pointer text
reproduces the exact same warnings/line numbers seen in the CI log. This
points to a transient LFS fetch/smudge failure in that specific CI run, not
a defect in the page or the committed images — re-running the job should
clear it.

Verification data

No datasheet exists for this kit (checked the ADI PDF sitemap and
adoc search-wiki, no hits), and the page is not a dokuwiki import, so
there was no external source to diff against. Verification was limited to
rebuilding the page (adoc serve --once --sparse solutions/reference-designs/eval-ltpa-lnakit and cd docs && make dirhtml), inspecting the generated HTML to confirm the new :numref:
resolves to "Figure 6", and running vale --config=.github/styles/vale-spelling.ini
before/after the fix.

Suggested patches

• 0001-fixup-solutions-ref-designs-added-EVAL-LTPA-LNAKIT-d.patch (e930794) — fixes the dangling figure reference, the broken :ez: role target, two typos, and whitespace cleanup.

can we remove all :scale:, it is not used anywhere else.

[ALUyie]

Apologies for the delay. All instances of :scale: have been removed.

[gastmaier]

Are those "wiki to .rst" conversion artifacts? please clean-up

[ALUyie]

Cleaned up now. Thanks!
