PSIL: Configuration accesses and source thread teardowns may cause data corruption
When performing a tear down on one source thread, a single data phase on a different source thread may be lost. This affects all PSIL_ENDPT modules that have more than 1 source thread (ICSSG/CSI/SA2UL)
Also, if a configuration response is sent out by a PSIL Endpoint Gasket while data is also being sent out, the response will cause data corruption. This can affect data transmitted long after the configuration response occurs. This affects all PSIL_ENDPT users that require width adaption where their PSIL port is less than 128-bit (SA2UL).
All PSIL source threads must be idled by disabling the source of Rx traffic before attempting a configuration access or a teardown of any source thread. For ICSSG/CSI, idling of PSIL source threads can also be done by pausing all source threads.
