Subject: [PATCH v1 1/1] arm64: dts: qcom: x1e80100-lenovo-yoga-slim7x: enable MICs LDO
Date: Fri, 11 Apr 2025 17:54:21 +0200 [thread overview]
Message-ID: <20250411155852.4238-1-alex.vinarskis@gmail.com> (raw)
Particular device comes without headset combo jack, hence does not
feature wcd codec IC. In such cases, DMICs are powered from vreg_l1b.
Set regulator as always-on to enable microphones.
