The system configuration controller is mainly used to manage the compensation cell and other IOs and system related settings. The SYSCFG driver is in charge of configuring masters on the interconnect, IO compensation, low voltage boards, or pull-ups for boot pins. All other configurations should be handled in Linux drivers requiring it. Device tree files are also updated to manage vdd-supply regulator.
