Subject: [PATCH] arm64: dts: qcom: sdm845-db845c: Move LVS regulator nodes up
Date: Fri,  2 Jun 2023 21:42:46 +0530	[thread overview]
Message-ID: <20230602161246.1855448-1-amit.pundir@linaro.org> (raw)

Move lvs1 and lvs2 regulator nodes up in the rpmh-regulators
list to workaround a boot regression uncovered by the upstream
commit ad44ac082fdf ("regulator: qcom-rpmh: Revert "regulator:
qcom-rpmh: Use PROBE_FORCE_SYNCHRONOUS"").

Without this fix DB845c fail to boot at times because one of the
lvs1 or lvs2 regulators fail to turn ON in time.
