Subject: [PATCH v1 5/6] arm64: dts: librem5-devkit: Add mux for built-in vs headset mic
Date: Sun, 21 Feb 2021 12:07:10 +0100	[thread overview]
Message-ID: <cdd0c4f966fd425425c056043d8672334b49d32b.1613905397.git.agx@sigxcpu.org> (raw)
In-Reply-To: <cover.1613905396.git.agx@sigxcpu.org>

Add mux so we can select either headset or built-in microphone input.
