Subject: [PATCH] arm64: dts: qcom: x1e78100-t14s: add sound support
From: Srinivas Kandagatla <srinivas.kandagatla@...aro.org>
Add support for audio on Lenovo T14s laptop, coming with two speakers,
audio jack and two digital microphones.
This is very early work, not yet complete:
1. 2x speakers: work OK.
2. 2x digital microphones: work OK.
3. Headset (audio jack) recording: does not work.
4. Headphones playback (audio jack): channels are intermixed.
Signed-off-by: Srinivas Kandagatla <srinivas.kandagatla@...aro.org>
[krzysztof: correct DMIC routing and vamacro pinctrl, re-order nodes,
add commit msg]
Co-developed-by: Krzysztof Kozlowski <krzysztof.kozlowski@...aro.org>

1. Audioreach topology was already pushed to main branch:
https://github.com/linux-msm/audioreach-topology
2. ALSA UCM files are ready and soon will be pushed by Srini.
