The status field of the Transfer Not Read event is different on Control Endpoints. On this patch we are just adding the defines to be used on a later patch which will re-work the control endpoint handling. Signed-off-by:Felipe Balbi <balbi@ti.com>

Type 6 should be used for the first transfer during an interval. This is also what the reference driver is using. Type 7 seems to be for following or additional transfers within the same interval. Signed-off-by:

If we collected two requests together (i.e. only the last of them has LST=1) then we only have to stop transfer once: The clean-up code will cleanup everything until first TRB with the LST bit set. After XferComplete this index should be no longer valid since there is no transfer pending. Signed-off-by:

A TRB which is dequeued seems to have its HWO bits set to 1. Therefore we ignore it if we dequeue it after the command is completed. Signed-off-by:

This patch changes rts51x_read_mem, rts51x_write_mem, and rts51x_read_status to allocate temporary buffers with kmalloc. This way stack addresses are not used for DMA when these functions call rts51x_bulk_transport. Signed-off-by:

Executing | testusb -a -c 1 -t 3 -v 421 -s 2048 does not complete on the gadget side. g_zero enqueues a 4096 bytes long buffer. The host sends 2048bytes which is a multiple of wMaxPacketSize (either 64 or 512 bytes). The host is done with sending data but the gadget waits for more. Since the protocol does not include transfer-length-field sending a terminating zero packet seems the only way out. Reviewed-by:

When a low or full speed urb in progress is unlinked (or some other error occurs), the buffer in the transaction translator (part of the hub) might end up in an inconsistent state. This can make all further low and full speed transactions fail, unless the buffer is cleared. The bug can be seen when running the usbtest unlink tests as "set altsetting to 0 failed, -110", and gets fixed by this patch. Signed-off-by:

The usb-interrupt is requested before the endpoints are initalised. If an interrupt happens in the time between request_irq and the init of the endpoint-data (as seen on the Qisda ESx00 ebook-platforms), it is therefore possible for the interrupt handler to access endpoint- data before its creation resulting in a null-pointer dereference. This patch simply moves the irq request below the endpoint init. Signed-off-by:

The DesignWare USB3 is a highly configurable IP Core which can be instantiated as Dual-Role Device (DRD), Peripheral Only and Host Only (XHCI) configurations. Several other parameters can be configured like amount of FIFO space, amount of TX and RX endpoints, amount of Host Interrupters, etc. The current driver has been validated with a virtual model of version 1.73a of that core and with an FPGA burned with version 1.83a of the DRD core. We have support for PCIe bus, which is used on FPGA prototyping, and for the OMAP5, more adaptation (or glue) layers can be easily added and the driver is half prepared to handle any possible configuration the HW engineer has chosen considering we have the information on one of the GHWPARAMS registers to do runtime checking of certain features. More runtime checks can, and should, be added in order to make this driver even more flexible with regards to number of endpoints, FIFO sizes, transfer types, etc. While this supports only the device side, for now, we will add support for Host side (xHCI - see the updated series Sebastian has sent [1]) and OTG after we have it all stabilized.

This patch (as1483) improves the ehci-hcd driver family by getting rid of the reliance on the hcd->state variable. It has no clear owner and it isn't protected by the usual HCD locks. In its place, the patch adds a new, private ehci->rh_state field to record the state of the root hub. Along the way, the patch removes a couple of lines containing redundant assignments to the state variable. Also, the QUIESCING state simply gets changed to the RUNNING state, because the driver doesn't make any distinction between them. Signed-off-by:

Errata 2 for the isp1760 explains that the chip sometimes does not issue interrupts when an ATL (bulk or control) transfer is completed. There are several issues with the current work-around (SOF interrupts) for this: 1) It seems the chip sometimes does not even set the done bit for a completed transfer, in which case SOF interrupts does not solve the problem since we still check the done map to find out which transfer descriptors to handle. 2) The above point seems to happen only when ATL and SOF interrupts are enabled at the same time. However, disabling ATL interrupts increases the latency between transfer completion and handling. This is very noticeable in the testusb suite, which take several minutes more to run with ATL interrupts disabled. This patch removes the code to switch on SOF interrupts, and instead use a kernel timer to periodically check for "old" descriptors that have their VALID and ACTIVE flags unset, indicating completion, thus avoiding the dependency on the chip's done map (and SOF interrupts) to find transfers affected by this HW bug.
