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.
