[PATCH 1/8] usb: dwc3: gadget: fix ISOC TRB type on unaligned transfers

When chaining ISOC TRBs together, only the first ISOC TRB should be of type ISOC_FIRST, all others should be of type ISOC. This patch fixes that. Fixes: c6267a51639b ("usb: dwc3: gadget: align transfers to wMaxPacketSize") Cc: # v4.11+ Signed-off-by: Felipe Balbi --- drivers/usb/dwc3/gadget.c |

[PATCH 3/8] usb: dwc3: gadget: track number of TRBs per request

This will help us remove the wait_event() from our ->dequeue(). Signed-off-by: Felipe Balbi --- drivers/usb/dwc3/core.h | 3 +++ drivers/usb/dwc3/gadget.c | 6 ++ 2 files changed, 9 insertions(+) diff --git a/drivers/usb/dwc3/core.h b/drivers/usb/dwc3/core.h index 4872cba8699b..0de78cb29f

[PATCH 2/8] usb: dwc3: gadget: combine unaligned and zero flags

Both flags are used for the same purpose in dwc3: appending an extra TRB at the end to deal with controller requirements. By combining both flags into one, we make it clear that the situation is the same and that they should be treated equally. Signed-off-by: Felipe Balbi --- drivers/usb/dwc3/co

[PATCH 4/8] usb: dwc3: gadget: use num_trbs when skipping TRBs on ->dequeue()

Now that we track how many TRBs a request uses, it's easier to skip over them in case of a call to usb_ep_dequeue(). Let's do so and simplify the code a bit. Signed-off-by: Felipe Balbi --- drivers/usb/dwc3/gadget.c | 28 1 file changed, 4 insertions(+), 24 deletions

[PATCH 6/8] usb: dwc3: gadget: introduce cancelled_list

This list will host cancelled requests who still have TRBs being processed. Signed-off-by: Felipe Balbi --- drivers/usb/dwc3/core.h | 2 ++ drivers/usb/dwc3/gadget.c | 1 + drivers/usb/dwc3/gadget.h | 15 +++ 3 files changed, 18 insertions(+) diff --git a/drivers/usb/dwc3/core.h

[PATCH 5/8] usb: dwc3: gadget: extract dwc3_gadget_ep_skip_trbs()

Extract the logic for skipping over TRBs to its own function. This makes the code slightly more readable and makes it easier to move this call to its final resting place as a following patch. Signed-off-by: Felipe Balbi --- drivers/usb/dwc3/gadget.c | 61 +++

[PATCH 7/8] usb: dwc3: gadget: move requests to cancelled_list

Whenever we have a request in flight, we can move it to the cancelled list and later simply iterate over that list and skip over any TRBs we find. Signed-off-by: Felipe Balbi --- drivers/usb/dwc3/gadget.c | 17 ++--- 1 file changed, 14 insertions(+), 3 deletions(-) diff --git a/driv

[PATCH 8/8] usb: dwc3: gadget: remove wait_end_transfer

Now that we have a list of cancelled requests, we can skip over TRBs when END_TRANSFER command completes. Signed-off-by: Felipe Balbi --- drivers/usb/dwc3/core.h | 3 --- drivers/usb/dwc3/gadget.c | 40 +-- 2 files changed, 1 insertion(+), 42 deletions(-)
