2016-11-01usb: gadget: u_ether: remove interrupt throttlingFelipe Balbi
According to Dave Miller "the networking stack has a hard requirement that all SKBs which are transmitted must have their completion signalled in a fininte amount of time. This is because, until the SKB is freed by the driver, it holds onto socket, netfilter, and other subsystem resources." In summary, this means that using TX IRQ throttling for the networking gadgets is, at least, complex and we should avoid it for the time being.

2016-10-31usb: dwc3: debug: move dwc3_ep0_state_string() to debug.hFelipe Balbi
We will be using dwc3_ep0_state_string() from within our tracepoints, so we need to move that helper to debug.h in order for it to be accessible. Signed-off-by: Felipe Balbi <felipe.balbi@linux.intel.com>

DWC3 can tell us which phase of a setup transfer we're getting into. Let's decode it from the event to make it easier to debug. Signed-off-by: Felipe Balbi <felipe.balbi@linux.intel.com>
2016-10-31usb: dwc3: gadget: conditionally disable Link State change eventsFelipe Balbi
Link State Change events are only needed for debugging and to apply certain workarounds on known errata. Let's save a few cycles by disabling these events completely on working revisions of the core. Signed-off-by: Felipe Balbi <felipe.balbi@linux.intel.com>
2016-10-31usb: dwc3: gadget: giveback request if we can't kick itFelipe Balbi
There might be situations where a Start Transfer command might fail, if that ever happens, instead of simply removing the request from our list, we should give the request back to the gadget driver, otherwise we might eventually starve it from requests. Signed-off-by: Felipe Balbi <felipe.balbi@linux.intel.com>
2016-10-31usb: dwc3: gadget: make use of No Response Update TransferFelipe Balbi
No Response Update Transfer is a special type of Update Transfer command which can be used whenever we're not relying on XferNotReady to prepare transfers. With this, we don't need to wait for CMDACT to be cleared and issue further commands to the endpoint straight away. Let's start using this version to skip the long-ish wait.

2016-10-31usb: dwc3: gadget: properly check ep cmdFelipe Balbi
The cmd argument we pass to dwc3_send_gadget_ep_cmd() could contain extra arguments embedded. When checking for StartTransfer command, we need to make sure to match only lower 4 bits which contain the actual command and ignore the rest.

2016-10-31usb: dwc3: gadget: set PCM1 field of isochronous-first TRBsFelipe Balbi
In case of High-Speed, High-Bandwidth endpoints, we need to tell DWC3 that we have more than one packet per interval. We do that by setting PCM1 field of Isochronous-First TRB. Cc: <stable@vger.kernel.org> Signed-off-by: Felipe Balbi <felipe.balbi@linux.intel.com>
2016-10-31usb: gadget: composite: always set ep->mult to a sensible valueFelipe Balbi
ep->mult is supposed to be set to Isochronous and Interrupt Endapoint's multiplier value. This value is computed from different places depending on the link speed. If we're dealing with HighSpeed, then it's part of bits [12:11] of wMaxPacketSize. This case wasn't taken into consideration before. While at that, also make sure the ep->mult defaults to one so drivers can use it unconditionally and assume they'll never multiply ep->maxpacket to zero.

2016-10-31usb: gadget: composite: correctly initialize ep->maxpacketFelipe Balbi
usb_endpoint_maxp() returns wMaxPacketSize in its raw form. Without taking into consideration that it also contains other bits reserved for isochronous endpoints. This patch fixes one occasion where this is a problem by making sure that we initialize ep->maxpacket only with lower 10 bits of the value returned by usb_endpoint_maxp(). Note that seperate patches will be necessary to audit all call sites of usb_endpoint_maxp() and make sure that usb_endpoint_maxp() only returns lower 10 bits of wMaxPacketSize.
