2010-10-22USB: qcserial: Enable Diagnostics Monitor and GPS ports on Gobi 2000Matthias G. Eckermann
this patch to qcserial.c enables the Diagnostics Monitor and NMEA GPS ports on Qualcomm Gobi 2000 devices. A Gobi 2000 device will provide 3 serial ports: # /dev/ttyUSB0 -> Diagnostics # /dev/ttyUSB1 -> 3G Modem # /dev/ttyUSB2 -> NMEA GPS port * The Diagnostics Monitor uses Qualcomm's DM protocol; I used libqcdm (ModemManager) to talk to it, found it working, but at least DM commands 12 and 64 are not implemented on my device (Gobi 2000 built into Thinkpad x100e). * Functionality of the 3G Modem port remains unchanged. * The GPS port and how to enable it has been confirmed now in the Gobi 3000 source code at: https://www.codeaurora.org/patches/quic/gobi/ Enable/disable GPS via: echo "\$GPS_START" > /dev/ttyUSB2 # use GPS echo "\$GPS_STOP" > /dev/ttyUSB2 Signed-off-by: Matthias G.

2010-10-22USB: ftdi_sio: revert "USB: ftdi_sio: fix DTR/RTS line modes"Johan Hovold
This reverts commit 6a1a82df91fa0eb1cc76069a9efe5714d087eccd. RTS and DTR should not be modified based on CRTSCTS when calling set_termios. Modem control lines are raised at port open by the tty layer and should stay raised regardless of whether hardware flow control is enabled or not. This is in conformance with the way serial ports work today and many applications depend on this behaviour to be able to talk to hardware implementing hardware flow control (without the applications actually using it). Hardware which expects different behaviour on these lines can always use TIOCMSET/TIOCMBI[SC] after port open to change them.

2010-10-22USB: option: Add new ONDA vendor id and product id for ONDA MT825UPEnrico Mioso
This patch, adds to the option driver the Onda Communication (http://www.ondacommunication.com) vendor id, and the MT825UP modem device id. Note that many variants of this same device are being release here in Italy (at least one or two per telephony operator). These devices are perfectly equivalent except for some predefined settings (which can be changed of course). It should be noted that most ONDA devices are allready supported (they used other vendor's ids in the past). The patch seems working fine here, and the rest of the driver seems uninfluenced.

2010-10-22USB: option: Add more ZTE modem USB id'sMauro Carvalho Chehab
There are lots of ZTE USB id's currently not covered by usb/serial. Adds them, to allow those devices to work properly on Linux. While here, put the USB ID's for 0x2002/0x2003 at the sorted order. This patch is based on zte.c file found on MF645. PS.: The ZTE driver is commenting the USB ID for 0x0053. It also adds, commented, an USB ID for 0x0026. Not sure why, but I think that 0053 is used by their devices in storage mode only. So, I opted to keep the comment on this patch.

2010-10-22OHCI: work around for nVidia shutdown problemAlan Stern
This patch (as1417) fixes a problem affecting some (or all) nVidia chipsets. When the computer is shut down, the OHCI controllers continue to power the USB buses and evidently they drive a Reset signal out all their ports. This prevents attached devices from going to low power. Mouse LEDs stay on, for example, which is disconcerting for users and a drain on laptop batteries. The fix involves leaving each OHCI controller in the OPERATIONAL state during system shutdown rather than putting it in the RESET state. Although this nominally means the controller is running, in fact it's not doing very much since all the schedules are all disabled. However there is ongoing DMA to the Host Controller Communications Area, so the patch also disables the bus-master capability of all PCI USB controllers after the shutdown routine runs. The fix is applied only to nVidia-based PCI OHCI controllers, so it shouldn't cause problems on systems using other hardware. As an added safety measure, in case the kernel encounters one of these running controllers during boot, the patch changes quirk_usb_handoff_ohci() (which runs early on during PCI discovery) to reset the controller before anything bad can happen.

2010-10-22USB: ehci tdi : let's tdi_reset set host modeMatthieu CASTET
tdi_reset is already taking care of setting host mode for tdi devices. Don't duplicate code in platform driver. Make ehci_halt a nop if the controller is not in host mode (otherwise it will fail), and let's ehci_reset do the tdi_reset. We need to move hcd->has_tt flags before ehci_halt, in order ehci_halt knows we are a tdi device. Before the setup routine was doing : - put controller in host mode - ehci_halt - ehci_init - hcd->has_tt = 1; - ehci_reset Now we do : - hcd->has_tt = 1; - ehci_halt - ehci_init - ehci_reset PS : now we handle correctly the device -> host transition.

2010-10-22USB: gadget: composite: Better string override handlingMichal Nazarewicz
The iManufatcurer, iProduct and iSerialNumber composite module parameters were only used when the gadget driver registers strings for manufacturer, product and serial number. If the gadget never bothered to set corresponding fields in USB device descriptors those module parameters are ignored. This commit makes the parameters work even if the strings ID have not been assigned. It also changes the way IDs are overridden -- what IDs are overridden is now saved in usb_composite_dev structure -- which makes it unnecessary to modify the string tables the way previous code did. The commit also adds a iProduct and iManufatcurer fields to the usb_composite_device structure. If they are set, appropriate strings are reserved and added to device descriptor. This makes it unnecessary for gadget drivers to maintain code for setting those. If iProduct is not set it defaults to usb_composite_device::name; if iManufatcurer is not set a default "<system> <release> with <gadget-name>" is used. The last thing is that if needs_serial field of usb_composite_device is set and user failed to provided iSerialNumber parameter a warning is issued.

This adds support for the USB transceiver driver in the Langwell chipset used on the Intel MID platforms. It folds up the original patch set which includes basic support for the device, PHY low power mode (Please notice that there is a limitation, after we drive VBus down, 2ms delay is required from SCU FW to sync up OTGSC register with USBCFG register), software timers (the hardware timers do not work in low power mode), HNP, SRP.
