From b540b4e157c4b24d0501e5e50ffba598d066de42 Mon Sep 17 00:00:00 2001 From: Jon Hunter Date: Thu, 8 Jan 2026 14:31:58 +0000 Subject: [PATCH] ASoC: dt-bindings: realtek,rt5640: Document port node Various boards that use the rt5640 audio codec define a 'port' child node under the codec node to describe the interface between it and the SoC that it is connected to. The binding document for the rt5640 codec does not define the 'port' child node and so this is generating warnings when running the DTB checks for these boards. Add the 'port' node to the binding document for the rt5640 codec to fix this.
