Subject: [PATCH v2 09/11] clk: qcom: mmcc-msm8998: Set bimc_smmu_gdsc always on
Date: Thu, 14 Jan 2021 23:10:57 +0100 [thread overview]
Message-ID: <20210114221059.483390-10-angelogioacchino.delregno@somainline.org> (raw)
In-Reply-To: <20210114221059.483390-1-angelogioacchino.delregno@somainline.org>
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.
