Quoting AngeloGioacchino Del Regno (2021-01-14 14:10:57)

This GDSC enables (or cuts!) power to the Multimedia Subsystem IOMMU
(mmss smmu), which has bootloader pre-set secure contexts.
In the event of a complete power loss, the secure contexts will be
reset and the hypervisor will crash the SoC.

To prevent this, and get a working multimedia subsystem, set this
GDSC as always on.
