usb: dwc3: Make TX/RX threshold configurable 2018-03-22T08:48:57+00:00 Thinh Nguyen Thinh.Nguyen@synopsys.com 2018-03-16T22:35:38+00:00 48f80609e536bc9be12c64e4c6c69625baee7b02 DWC_usb31 periodic transfer at 48K+ bytes per interval may need modification to the TX/RX packet threshold to achieve optimal result. Add properties to make it configurable. By default, periodic ESS TX and RX threshold are not enabled. To enable TX or RX threshold (host mode only), both packet threshold count and max burst size properties must be set to a valid non-zero value 1-16.
