Subject: [PATCH 08/11] arm64: dts: qcom: sdm670-google: add sound card
Date: Mon, 21 Sep 2026 21:57:58 -0400
Message-ID: <20260922015801.32373-9-mailingradian@gmail.com>

The Pixel 3a has a sound card for built-in audio (RT5514 and CS35L36
codecs) and for the headphone jack (WCD codec). Add the sound card and
q6asm frontends, which can route simultaneously between the RT5514
microphone, CS35L36 stereo speakers, headset audio playback, and headset
audio capture.
