-Subject: [PATCH 06/76] 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.
