MediaTek bus fabric provides TrustZone security support and data protection to prevent slaves from being accessed by unexpected masters. The security violation is logged and sent to the processor for further analysis or countermeasures. Any occurrence of security violation would raise an interrupt, and it will be handled by mtk-devapc driver. The violation information is printed in order to find the murderer.

2020-04-13soc / drm: mediatek: Fix mediatek-drm device probingEnric Balletbo i Serra
In the actual implementation the same compatible string "mediatek,<chip>-mmsys" is used to bind the clock drivers (drivers/soc/mediatek) as well as to the gpu driver (drivers/gpu/drm/mediatek/mtk_drm_drv.c). This ends with the problem that the only probed driver is the clock driver and there is no display at all. In any case having the same compatible string for two drivers is not correct and should be fixed. To fix this, and maintain backward compatibility, we can consider that the mmsys driver is the top-level entry point for the multimedia subsystem, so is not a pure clock controller but a system controller, and the drm driver is instantiated by that MMSYS driver.

2020-04-13clk / soc: mediatek: Move mt8173 MMSYS to platform driverMatthias Brugger
There is no strong reason for this to use CLK_OF_DECLARE instead of being a platform driver. Plus, MMSYS provides clocks but also a shared register space for the mediatek-drm and the mediatek-mdp driver. So move the MMSYS clocks to a new platform driver and also create a new MMSYS platform driver in drivers/soc/mediatek that instantiates the clock driver.
