The fifo_mode parameter is used to select endpoint allocation mode.
fifo_mode = 0 is used to let the driver autoconfigure the endpoints.
- In this case 2 banks are allocated for isochronous endpoints and
- only one bank is allocated for the rest of the endpoints.
+ In this case, for ep1 2 banks are allocated if it works in isochronous
+ mode and only 1 bank otherwise. For the rest of the endpoints
+ only 1 bank is allocated.
fifo_mode = 1 is a generic maximum fifo size (1024 bytes) configuration
allowing the usage of ep1 - ep6
