[PATCH v1 11/15] arm64: dts: qcom: sdm845-db845c: switch bt+wifi to qca power sequencer

From: Dmitry Baryshkov <hidden>
Date: 2021-10-06 03:55:43
Also in: linux-arm-msm, linux-bluetooth, linux-mmc, lkml, netdev
Subsystem: arm/qualcomm mailing list, arm/qualcomm support, the rest · Maintainers: Bjorn Andersson, Konrad Dybcio, Linus Torvalds

Switch sdm845-db845c device tree to use new power sequencer driver
rather than separate regulators.
