Thank you for your contribution! Sashiko AI review found 1 potential issue(s) to consider:
- [Medium] The dt-schema incorrectly uses an object schema for `additionalProperties` to define child LED nodes instead of `patternProperties`.

dt-bindings: leds: lacie,netxbig-leds: Convert to DT schema
This commit converts the lacie,netxbig-leds devicetree binding from the
legacy text format to DT schema.

[Severity: Medium]
Will this strict additionalProperties definition cause standard device tree
properties to fail validation?
Because additionalProperties is defined as an object schema here, any
top-level property added to the netxbig-leds node that isn't explicitly
defined (like status = "okay" or pinctrl-0) will be forced to evaluate
as an object, triggering schema validation errors for strings or arrays.
Should child LED nodes be defined using patternProperties instead, so that
standard node properties are not caught by this block?

This should be after the block defining the child nodes.

This is not how the child nodes should be implmeneted, it should use
pattenProperties instead.

This should IMO be additionalProperties: false, and the two option
properties that are supported explicitly cited.
The rest of this looks fine I think.
