weiyi.lu@mediatek.com	fa7e843a90	soc: mediatek: extend bus protection API ... MT2712 add "set/clear" bus control register to each control register set instead of providing only one "enable" control register, we could avoid the read-modify-write racing by declaring "bus_prot_reg_update" as "false" in scp_soc_data or declaring as "true" to use the legacy update method. By improving the mtk-infracfg bus protection implementation to support set/clear bus protection control method by IC configuration.

Sascha Hauer	16a624a9c8	soc: mediatek: Add infracfg misc driver support ... This adds support for some miscellaneous bits of the infracfg controller. The mtk_infracfg_set/clear_bus_protection functions are necessary for the scpsys power domain driver to handle the bus protection bits which are contained in the infacfg register space.
