PRODUCTION DATA
The SPMI bus is used to carry two types of information:
The SPMI controller device reads the TID of the target devices periodically to check the health of the interface. Exchanging Trigger IDs for the power state transition is sufficient to keep the PFSMs of all the devices on the SPMI network in synchronization. Device interrupts explain reason for the power state transitions.
