Changes in version 2:
Added cover letter for patch set
Done small,but significant changes in interrupt handlers, which will allow
to minimize incomplete ISOC IN/OUT, GOUTNAKEFF interrupt handling.
Razmik Karapetyan (3):
usb: dwc2: Update dwc2_handle_incomplete_isoc_in() function
usb:
In 'for' loop skipped masked and non-ISOC EPs. Also breaked 'for' loop
after setting SGOUTNAK in DCTL,when one enabled EP was detected.
This will allow to minimize incomplete ISOC OUT interrupt handling.
