* USB: EHCI: add symbolic constants for QHsAlan Stern2012-07-16
| | | | | | | | | This patch (as1568) introduces symbolic constants for some of the less-frequently used bitfields in the QH structure. This makes the code a little easier to read and understand.

* USB: EHCI: don't refcount QHsAlan Stern2012-07-16
| | | | | | | | | | | This patch (as1567) removes ehci-hcd's reference counting of QH structures. It's not necessary to refcount these things because they always get deallocated at exactly one spot in ehci_endpoint_disable() (except for two special QHs, ehci->async and ehci->dummy) and are never used again.

* USB: EHCI: remove unneeded suspend/resume codeAlan Stern2012-07-16
| | | | | | | | | | This patch (as1566) removes the code in ehci-hcd's resume routines which tries to restart or cancel any transfers left active while the root hub or controller was asleep. This code isn't necessary, because all URBs are terminated before the root hub is suspended.

* USB: EHCI: initialize data before resetting hardwareAlan Stern2012-07-16
| | | | | | | | | | | | | Currently, EHCI initialization turns off the controller (in case it was left running by the firmware) before setting up the ehci_hcd data structure. This patch (as1565) reverses that order. Although it doesn't matter now, it will matter later on when future additions to ehci_halt() will want to acquire a spinlock that gets initialized by ehci_init().

| * EHCI: centralize controller initializationAlan Stern2012-07-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as1564c) converts the EHCI platform drivers to use the central ehci_setup() routine for generic controller initialization rather than each having its own idiosyncratic approach. The major point of difficulty lies in ehci-pci's many vendor- and device-specific workarounds. Some of them have to be applied before calling ehci_setup() and some after, which necessitates a fair amount of code motion. The other platform drivers require much smaller changes. One point not addressed by the patch is whether ports should be powered on or off following initialization. The different drivers appear to handle this pretty much at random. In fact it shouldn't matter, because the hub driver turns on power to all ports when it binds to the root hub. Straightening that out will be left for another day.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as1563) removes a lot of duplicated code by moving the EHCI controller suspend/resume routines into the core driver, where the various platform drivers can invoke them as needed. Not only does this simplify these platform drivers, this also makes it easier for other platform drivers to add suspend/resume support in the future. Note: The patch does not touch the ehci-fsl.c file, because its approach to suspend and resume is so different from all the others. It will have to be handled specially by its maintainer.

| * usbdevfs: Use scatter-gather lists for large bulk transfersHans de Goede2012-07-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When using urb->transfer_buffer we need to allocate physical contiguous buffers for the entire transfer, which is pretty much guaranteed to fail with large transfers. Currently userspace works around this by breaking large transfers into multiple urbs. For large bulk transfers this leads to all kind of complications. This patch makes it possible for userspace to reliable submit large bulk transfers to scatter-gather capable host controllers in one go, by using a scatterlist to break the transfer up in managable chunks.

| * usbdevfs: Add a USBDEVFS_GET_CAPABILITIES ioctlHans de Goede2012-07-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are a few (new) usbdevfs capabilities which an application cannot discover in any other way then checking the kernel version. There are 3 problems with this: 1) It is just not very pretty. 2) Given the tendency of enterprise distros to backport stuff it is not reliable. 3) As discussed in length on the mailinglist, USBDEVFS_URB_BULK_CONTINUATION does not work as it should when combined with USBDEVFS_URB_SHORT_NOT_OK (which is its intended use) on devices attached to an XHCI controller. So the availability of these features can be host controller dependent, making depending on them based on the kernel version not a good idea. This patch besides adding the new ioctl also adds flags for the following existing capabilities: USBDEVFS_CAP_ZERO_PACKET, available since 2.6.31 USBDEVFS_CAP_BULK_CONTINUATION, available since 2.6.32, except for XHCI USBDEVFS_CAP_NO_PACKET_SIZE_LIM, available since 3.3 Note that this patch only does not advertise the USBDEVFS_URB_BULK_CONTINUATION cap for XHCI controllers, bulk transfers with this flag set will still be accepted when submitted to XHCI controllers. Returning -EINVAL for them would break existing apps, and in most cases the troublesome scenario wrt USBDEVFS_URB_SHORT_NOT_OK urbs on XHCI controllers will never get hit, so this would break working use cases. The disadvantage of not returning -EINVAL is that cases were it is causing real trouble may go undetected / the cause of the trouble may be unclear, but this is the best we can do.

The bulk of changes is related to mis-defined macros which were never used before, some fixes to error path which e.g. prevent the driver from initiating two transfer on ep0out in case of stall, some fixes to request dequeueing and the End Transfer Command. We have some changes to U1/U2 handling where we were enabling those transtions at the wrong spot (though we haven't seen a problem from that as of today). A few patches will make it easier to add support for newer releases of the core by adding definitions for new registers and changing the code to act accordingly when certain revisions are detected. There's also the usual comestic changes to make the driver easier to maintain and make it easier for new- comers to understand the driver. Also one patch fixing a double inclusion of a header.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Although timeout has never been experienced, still to make it meaningful, its better to return error if it ever occurs. Signed-off-by: Pratyush Anand <pratyush.anand@st.com> Signed-off-by: Felipe Balbi <balbi@ti.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As per databook, ACCEPT{U1,U2}ENA bits should be set after receiving SetConfiguration Command. Signed-off-by: Pratyush Anand <pratyush.anand@st.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
| | * | usb: dwc3: no need to clear INIT{U1,U2}ENA bitsPratyush Anand2012-07-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | as per databook, these bits are cleared by hardware on each USB reset, so no need to clear it explicitly by software in reset ISR. Signed-off-by: Pratyush Anand <pratyush.anand@st.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
