* usb: musb: Fix hub port setting for SPLIT transactionsStefan Brüns2015-12-311-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | The ifdef'ed Linux kernel code uses the 1 based port number, whereas U-Boot puts a 0 based port number into the register. The reason the 0 based port number apparently works can probably be taken from the USB 2.0 spec: 8.4.2.2 Start-Split Transaction Token ... The host must correctly set the port field for single and multiple TT hub implementations. A single TT hub implementation *may ignore* the port field. Actually, as far as I understand, a multi TT hub defaults to single TT (bAlternateSetting: 0) until switched via SetInterface, so even "port 42" would work. The change was verified by hardcoding the port number to a wrong value, SPLIT transactions kept working (although using a DWC2 instead of MUSB). Tested hubs are the RPi onboard SMC9514 and an external "05e3:0608 Genesys Logic, Inc. USB-2.0 4-Port HUB". The former is a multi TT hub, the latter single TT only.

* usb: Move determination of TT hub address/port into separate functionStefan Brüns2015-12-311-3/+7
| | | | | | | | | | | | | Start split and complete split tokens need the hub address and the downstream port of the first HS hub (device view). The core of the function was duplicated in both host/ehci_hcd and musb-new/usb-compat.h.

* musb: Update usb-compat to work with struct usb_device without a parent ptrHans de Goede2015-07-211-0/+4
| | | | | | | | When building with CONFIG_DM_USB=y struct usb_device does not have a parent pointer. This commit adds support to the musb code to deal with this. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Simon Glass <sjg@chromium.org>
* musb-new: Properly remove a transfer from the schedule on timeoutHans de Goede2015-01-181-3/+9
| | | | | | | | | | | If a transfer / urb times-out, properly remove it from the schedule, rather then letting it sit on the ep head. This stops the musb code from getting confused and refusing to queue further transfers after a timeout. Tested by unplugging a usb-keyboard, replugging it and doing a usb-reset, before this commit the keyboard would not work after the usb-reset. Signed-off-by: Hans de Goede <hdegoede@redhat.com>
* kbuild: force to define __UBOOT__ in all the C sourcesMasahiro Yamada2014-09-161-1/+0
| | | | | | | | | | | | | | | | | | | | | | | U-Boot has imported various source files from other projects, mostly Linux. Something like #ifdef __UBOOT__ [ modification for U-Boot ] #else [ original code ] #endif is an often used strategy for clarification of adjusted parts, that is, easier re-sync in future. Instead of defining __UBOOT__ in each source file, passing it from the top Makefile would be easier.

* musb-new: port of Linux musb driverIlya Yanok2012-11-201-0/+2400
Existing U-Boot musb driver has no support for the new gadget framework and also seems to have other limitations. As gadget framework is ported from Linux it seems pretty natural to port musb gadget driver as well. This driver supports both host and peripheral modes. This is not a replacement for current musb driver (at least now) as there are still some consumers of the old UDC interface. No DMA operation support included, CONFIG_MUSB_PIO_ONLY should be defined. Virtual root hub device is not implemented. Known problems: with no devices connected usb_lowlevel_start() fails. Signed-off-by: Ilya Yanok <ilya.yanok@cogentembedded.com>
