Subject: [PATCH v2] arm64: defconfig: enable regulator to fix mt8173 regression
Date: Fri, 29 Oct 2021 18:39:47 +0300 [thread overview]
Message-ID: <20211029153947.225416-1-adrian.ratiu@collabora.com> (raw)
A regression was introduced on some mediatek boards starting with
v5.15-rc1 in commit 109fd20601e2 ("arm64: dts: mediatek: mt8173:
Add domain supply for mfg_async") which effectively changed the
regulator from the always-on dummy to DA9211 without explicitely
enabling it, causing failures caught by KernelCI on Hana
Chromebooks [1] for previously used dummies like:
mtk-power-controller 10006000.syscon:power-controller: supply domain not found, using dummy regulator
mtu3 11271000.usb: supply vbus not found, using dummy regulator
xhci-mtk 11270000.usb: supply vbus not found, using dummy regulator
There might be another bug linking these power domains in the
mediatek PM driver, but that is a separate issue wich needs
addressing, for now just fix the obvious regression due to the
new regulator requirement.
