5.10-stable review patch. If anyone has any objections, please let me know. ------------------ From: AngeloGioacchino Del Regno <angelogioacchino.delregno@xxxxxxxxxxxxxx> [ Upstream commit 68e1d106eb4dceb61bc2818d829786b364fd502b ] 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.
