[PATCH net-next v3 2/3] dt-bindings: net: wiznet,w5100: add link-gpios

From: Arthur Crépin Leblond

Date: Thu Aug 06 2026 - 11:06:26 EST

Add the link-gpios property which describes an optional GPIO line that
can be wired to the LINKLED pin of the w5500 as an interrupt to detect
link status changes.
