[PATCH v2 6/6] arm64: dts: qcom: qcs6490-rubikpi3: Add audio support
From: Hongyang Zhao
Date: Wed Jul 15 2026 - 11:26:59 EST
RubikPi 3 uses the AudioReach firmware path for its external audio
interfaces. The primary MI2S interface connects to an ES8316 codec for
headset playback and capture, while the quaternary MI2S interface feeds
the LT9611 HDMI bridge.
Enable the AudioReach description and add the three DAI links. Describe
the primary MI2S MCLK and bit clock inputs under the backend DAI so the
machine driver can control them. Add the primary and quaternary pin
configurations to the sound card and make the LT9611 codec DAI
addressable.
Describe the ES8316, its 3.3 V enable supply, 19.2 MHz MCLK and inverted
GPIO jack-detect signal. Route the codec headphone outputs and microphone
input to the board headset connector.
