2013-10-20usb: ehci-hcd: add enum usb_init_type parameter to ehci_hcd_init.Troy Kisky
This paramter will later be used to initialize OTG ports in host or device mode. Signed-off-by: Troy Kisky <troy.kisky@boundarydevices.com>
2013-10-20usb: Move 'bmRequestType' USB device request macros from EHCI headerVivek Gautam
Macros defining bmRequestType field of USB device request, given in table 9.2 USB 2.0 spec, are rather generic macros which can be further used by other Host controller stacks. So moving them to usb_defs header.

2013-07-29usb: ehci: Split out struct ehci_ctrl definitionMarek Vasut
Move the struct ehci_ctrl defition from ehci-hcd.c into ehci.h so it can be re-used by drivers. In particular, the mv_udc driver can benefit from this move.

2013-03-18usb: ehci: Fix aliasing issue in EHCI interrupt codeVincent Palatin
The interrupt endpoint handling code stores the buffer pointer in the QH padding field. We need to make it the size of a pointer to avoid strict aliasing issue with the compiler. Signed-off-by: Vincent Palatin <vpalatin@chromium.org> Signed-off-by: Simon Glass <sjg@chromium.org>
2013-03-18usb: ehci: Support interrupt transfers via periodic listPatrick Georgi
Interrupt transfers aren't meant to be used from the async list (the EHCI spec indicates trouble with low/full-speed intr on async). Build a periodic list instead, and provide an API to make use of it. Then, use that API from the existing interrupt transfer API. This provides support for USB keyboards using EHCI. Use timeouts to ensure we cannot get stuck in the keyboard scanning if something wrong happens (USB device unplugged or fatal I/O error) Signed-off-by: Vincent Palatin <vpalatin@chromium.org> Signed-off-by: Julius Werner <jwerner@chromium.org> Signed-off-by: Simon Glass <sjg@chromium.org>
2012-10-15usb: ehci: rework to take advantage of new lowlevel interfaceLucas Stach
Kill off ehci-core.h It was used to specify some static controller data. To support more than one controller being active at any time we have to carry the controller data ourselfes. Change the ehci interface accordingly. NOTE: OMAP implemented the ehci stuff a bit backwards and should be fixed to do the same thing as other platforms. But the change for now is at least compile clean. Signed-off-by: Lucas Stach <dev@lynxeye.de> Reviewed-by: Marek Vasut <marex@denx.de>

2011-09-04USB: Remove __attribute__ ((packed)) for struct ehci_hccr and ehci_hcorJason Kridner
Remove __attribute__ ((packed)) to prevent byte access to soc registers in some gcc versions. Having patches to enable ehci for the BeagleBoard lying around for several months, this one was the show-stopper. Switched to align(4), rather than remove the attribute, per suggestion from Alexander. Credits have to go to Laine Walker-Avina <lwalkera@ieee.org> for finding the problem.

2010-10-22USB: fix Queue Element Transfer Descriptor changesWolfgang Denk
Commit 3ed1607 "USB: sync Queue Element Transfer Descriptor against EHCI spec" added an "__attribute__ ((aligned (32)))" to the declaration of struct qTD, as used for example in the Linux kernel as well. However, it turns out that this attribute causes errors in "usb start" (like "ERROR: NOT USB_CONFIG_DESC 7b" and similar). Drop the attribute again.

2010-10-20USB: sync Queue Element Transfer Descriptor against EHCI specWolfgang Denk
Appendix B "EHCI 64-Bit Data Structures" of the "Enhanced Host Controller Interface Specification for Universal Serial Bus" (Rev. 1.0, March 12, 2002) defines additional fields which were missing in U-Boot's struct qTD; as these are also present in recent versions of struct ehci_qtd in the Linux kernel, we add them here, too. This fixes some nasty memory corruption problems.
