From 66b47b9c069fa548db64bde6a32d3b33aa05f740 Mon Sep 17 00:00:00 2001 From: Jon Hunter Date: Thu, 8 Jan 2026 14:31:56 +0000 Subject: [PATCH] ASoC: dt-bindings: realtek,rt5640: Document mclk Commit eba5a0bac211 ("ASoC: dt-bindings: realtek,rt5640: Convert to dtschema") converted the rt5640 dt-binding to yaml format but in the process dropped 'clock' and 'clock-names' properties that are used to specify the codec 'mclk'. This is causing DTB build warnings for boards that use this codec and define an 'mclk' in device-tree. Update the rt5640 binding document to add the optional mclk.
