Subject: iommu/mediatek: Add SVP support for mt8188
Date: Mon, 11 Sep 2023 09:17:47 +0800 [thread overview]
Message-ID: <20230911011751.29906-1-yong.wu@mediatek.com> (raw)
This patchset adds support for SVP(Secure video play). We always use the
last bank(id:4) to map secure memory. But the detail mapping and control
information are in the TEE. In kernel, We just register the IRQ to report
specific information when secure translation fault occurs.
Base on v6.6-rc1.
Yong Wu (4):
iommu/mediatek: Initialise the secure bank
iommu/mediatek: Add irq handle for secure bank
iommu/mediatek: Avoid access secure bank register in runtime_suspend
iommu/mediatek: mt8188: Enable secure bank for MM IOMMU
