firmware: arm_scmi: Add RESET protocol in SCMI v2.0
SCMIv2.0 adds a new Reset Management Protocol to manage various reset states a given device or domain can enter. Device(s) that can be collectively reset through a common reset signal constitute a reset domain for the firmware. A reset domain can be reset autonomously or explicitly through assertion and de-assertion of the signal. When autonomous reset is chosen, the firmware is responsible for taking the necessary steps to reset the domain and to subsequently bring it out of reset. When explicit reset is chosen, the caller has to specifically assert and then de-assert the reset signal by issuing two separate RESET commands. Add the basic SCMI reset infrastructure that can be used by Linux reset controller driver. Reviewed-by:Peng Fan <peng.fan@nxp.com> Reviewed-by:
