Devices from the TI K3 family of SoCs like the AM654x contain a Device Management and Security Controller (SYSFW) that manages the low-level device control (like clocks, resets etc) for the various hardware modules present on the SoC. These device control operations are provided to the host processor OS through a communication protocol called the TI System Control Interface (TI SCI) protocol. This patch adds a system reset driver that communicates to the system controller over the TI SCI protocol for allowing to perform a system- wide SoC reset.
