[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,
This patchset consists of various bug fixes and feature enhancements for the
dwc2 gadget driver. All the patches are verified on dwc2 v3.0a with dedicated
fifos. Main focus of testing was with dma enabled. Although basic testing
without dma was also done.

It is based on testing/next branch in Felipe's git with
https://lkml.org/lkml/2014/12/16/135 applied on top.

Thank you,

Best regards,
Yousaf
