[PATCH v2] dt-bindings: leds: lacie,netxbig-leds: Convert to DT schema

From: Udaya Kiran Challa

Date: Fri Aug 21 2026 - 08:44:02 EST


Convert lacie,netxbig-leds devicetree binding from legacy
text format to DT schema.

Signed-off-by: Udaya Kiran Challa <challauday369@xxxxxxxxx>

Changelog:

Changes since v1:
- Use pattenProperties for LED child nodes instead of additionalProperties
- Explicitly list the two optional properties supported by the binding
- Place the top-level required block after child-node definition
