[PATCH v2 09/11] clk: qcom: mmcc-msm8998: Set bimc_smmu_gdsc always on

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
