From 3d7646cea76fc08126534b428b299c326b3c66ca Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?J=C3=A9r=C3=B4me=20de=20Bretagne?= Date: Thu, 4 Jun 2026 18:18:46 +0200 Subject: [PATCH] arm64: dts: qcom: sc8280xp-arcata: Drop duplicate DMIC supplies MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Align with the reference implementation from the ThinkPad X13s. The audio-routing setup specifies two power supplies for each DMIC, but only one of them can be active at the same time. Drop the redundant routes to the pull-up "VA MIC BIASn" supplies as done in commit a2e617f4e698 ("arm64: dts: qcom: sc8280xp-x13s: Drop duplicate DMIC supplies"). There is no functional difference except that we skip briefly switching to pull-up mode when shutting down the microphone.
