Isochronous transfers #1

Open mciantyre opened 3 years ago

mciantyre commented 3 years ago

The driver does not support isochronous transfers. As of this writing, there's no need to support these endpoints, since isochronous endpoints aren't supported in the usb-device ecosystem. However, a custom i.MX RT USB driver might need support for isochronous transfers. We should consider adding support once they're available in usb-device, or when considering a custom i.MX RT USB driver.

There is now some work on usb-device for isochronous, though it sounds like people are working out how to deal with DMA to improve it.
