Subject: [PATCH v2 0/7] usb: dwc3: gadget: Fix TRB preparation
Date: Thu, 06 Aug 2020 19:46:16 -0700 [thread overview]
Message-ID: <cover.1596767991.git.thinhn@synopsys.com> (raw)
There are a few issues in DWC3 driver when preparing for TRB.
The driver needs to account the following:
* MPS alignment for ZLP OUT direction
* Extra TRBs when checking for available TRBs
* SG entries size > request length
Along with these fixes, there are some cleanup/refactoring patches in this
series.
Changes in v2:
- Update remaining length when resume request
- Remove unused variables
- Add a missing "return 0" for dwc3_prepare_trbs()
- Update doc indicating dwc3_prepare_trbs() can return other -errno
