[PATCH 2/2] arm64: dts: qcom: sc8280xp-x13s: Add DP0/DP1 audio playback support
From: Jens Glathe via B4 Relay
Date: Thu Aug 27 2026 - 03:53:24 EST
From: Jens Glathe <jens.glathe@xxxxxxxxxxxxxxxxxxxxxx>
The X13s sound card has no DAI links for the Type-C DisplayPort
controllers, so those playback paths never show up. Add DP0 and DP1
links using the existing mdss0_dp DAIs and DISPLAY_PORT_RX_{0,1}.
