It needs to be very carefully for setting this property, it is recommended that consult with your IC engineer before setting this value. On the most of chipidea platforms, the "usage_tt" flag at RTL is 0, so this property only affects siTD. If this property is not set, the max packet size is 1023 bytes, and if the total of packet size for previous transactions are more than 256 bytes, it can't accept any transactions within this frame. The use case is single transaction, but higher frame rate. If this property is set, the max packet size is 188 bytes, it can handle more transactions than above case, it can accept transactions until it considers the left room size within frame is less than 188 bytes, software needs to make sure it does not send more than 90% maximum_periodic_data_per_frame. The use case is multiple transactions, but less frame rate. type: boolean mux-controls: description: The mux control for toggling host/device output of this controller.
