soc: mediatek: Add MediaTek DVFS Resource Collector (DVFSRC) driver

2024-10-21T14:00:51Z

The Dynamic Voltage and Frequency Scaling Resource Collector (DVFSRC) is a Hardware module used to collect all the requests from both software and the various remote processors embedded into the SoC and decide about a minimum operating voltage and a minimum DRAM frequency to fulfill those requests in an effort to provide the best achievable performance per watt. This hardware IP is capable of transparently performing direct register R/W on all of the DVFSRC-controlled regulators and SoC bandwidth knobs. This driver includes support for MT8183, MT8192 and MT8195.

memory: mtk-smi: Add enable IOMMU SMC command for MM master

2022-08-30T17:54:05Z

For concerns about security, the register to enable/disable IOMMU of SMI LARB should only be configured in secure world. Thus, we add some SMC command for multimedia master to enable/disable MM IOMMU in ATF by setting the register of SMI LARB. This function is prepared for MT8188.
