Re: [PATCH v5 1/6] dt-bindings: iio: dac: ad5504: add output-range and missing gpios

[sashiko-bot@kernel.org]

Thank you for your contribution! Sashiko AI review found 2 potential issue(s) to consider:
- [Medium] The `output-range-microvolt` property is defined with an `items` array but lacks `minItems: 2` and `maxItems: 2` constraints.
- [Medium] The `vlogic-supply` property is missing from the devicetree example, contradicting the commit message claim.

--- Patch [1]: [PATCH v5 1/6] dt-bindings: iio: dac: ad5504: add output-range and missing gpios ---
commit fae484c36ed84e118c97518d409f24eed9d5eadd
Author: Taha Ed-Dafili <0rayn.dev@gmail.com>
Subject: dt-bindings: iio: dac: ad5504: add output-range and missing gpios

This commit updates the AD5504 device tree binding to support output voltage
range selection via the R_SEL pin. It adds output-range-microvolt and missing
GPIO properties, enforces mutual exclusivity for range selection, and updates
the documentation with a usage example.

[Severity: Medium]
Should this property include minItems and maxItems constraints? Without 
explicit bounds like maxItems: 2, will arrays of arbitrary length or missing 
elements silently pass schema validation?

[Severity: Medium]
The commit message states this patch will "add missing vlogic-supply...
and provide a complete usage example." Is vlogic-supply intentionally omitted
from this example block?
