Subject: [PATCH v2 3/3] arm64: dts: allwinner: pinephone: Enable internal HMIC bias
Date: Mon, 20 Jun 2022 22:54:52 -0500 [thread overview]
Message-ID: <20220621035452.60272-4-samuel@sholland.org> (raw)
In-Reply-To: <20220621035452.60272-1-samuel@sholland.org>
Revisions 1.0 and 1.1 of the PinePhone mainboard do not have an external
resistor connecting HBIAS to MIC2P. Enable the internal resistor to
provide the necessary headeset microphone bias.
Signed-off-by: Samuel Holland <samuel@sholland.org>
