14 This driver provides the means of communicating with and controlling
15 the low-power state for resources related to the remoteproc
16 subsystems as well as controlling the debug clocks exposed by the Always On

24 Command DB queries shared memory by key string for shared system
25 resources. Platform drivers that require to set state of a shared
26 resource on a RPM-hardened platform must use this database to get
27 SoC specific identifier and information for the shared resources.
