[PATCH v6 3/4] usb: dwc3: Resize TX FIFOs to meet EP bursting requirements

2021-01-21 Thread Wesley Cheng
Some devices have USB compositions which may require multiple endpoints that support EP bursting. HW defined TX FIFO sizes may not always be sufficient for these compositions. By utilizing flexible TX FIFO allocation, this allows for endpoints to request the required FIFO depth to achieve higher
