[PATCH v7 06/11] arm64: dts: mediatek: set vmc regulator as always on

From: amergnat
Date: Thu May 11 2023 - 12:30:40 EST


From: Fabien Parent <fparent@xxxxxxxxxxxx>

On downstream, we observe that the MSDC IP (used by the emmc, the micro
SD card and the WiFi) isn't working properly if the VMC regulator is
shutdown.

Make sure it is always on.
