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.
