Patchset 1 introduces configuration of the cross-trigger registers with appropriate values to enable proper generation of cross-trigger packets. Patchset 2 introduces a function to configure the TPDA_SYNCR register, which determines the frequency of ASYNC packet generation. These packets assist userspace tools in accurately identifying each valid packet. Patchset 3 introduces a sysfs node to initiate a flush request for the specific port, forcing the data to synchronize and be transmitted to the sink device.
