[PATCH v3 5/8] arm64: dts: qcom: shikra-cqm-evk: Enable sound card support
From: Mohammad Rafi Shaik
Date: Thu Sep 17 2026 - 00:41:43 EST
Enable the sound card on the shikra-cqm-evk platform, including
the PM4125 (Rouleur) headset codec, WSA885x external speaker path,
and QAIF backend links.
Also enable the required LPASS macro and SoundWire nodes, along with
the necessary pinctrl configurations for DMIC and I2S interfaces.
