Presented patch series fix several problems with S3C-HSOTG driver, thus now
the Multi Function Gadget (MFG) is working correctly.
Those commits consist of EP0 transfer management fixes (ZLP sending code
and NAK management).
Moreover the disconnect irq handler has been removed.
Code for recovering from device disconnection and connection during ongoing
transfer has been added as well.
Patches done by Joonyoung Shim have been included to this patch series, since
those patches are necessary for further fixes. Unfortunately they haven't been
included to mainline yet.
Tested with:
- DFU gadget (various size of the sent data - also packet = MPS)
- Ethernet gadget (CDC and RNDIS)
- Multi Function Gadget (g_multi)
HW:
- Samsung's C210 Universal rev.0
