[PATCH v3 2/4] arm64: dts: qcom: add device tree for Asus Vivobook 16 X1607QA

From: Daniel Carter

Date: Fri Nov 13 2026 - 18:22:27 EST

Add initial device tree for the Asus Vivobook 16 X1607QA laptop
with the Snapdragon X X1P-42-100 (purwa) SoC, based on the Vivobook
S15. Includes the sound nodes (WSA8845 speakers, WCD938x codec via
SoundWire), the VA macro with its DMIC sample rate and mic bias
supply, and the EL2 device tree blob target.
