Since commit 461972d8 (musb_core: don't call musb_platform_exit() twice), unloading the driver module results in a WARNING "kobject: '(null)' (c73de788): is not initialized, yet kobject_put() is being called." (or even kernel oops) on e.g. DaVincis, though only in the OTG mode. There exists dubious and unbalanced put_device() call in musb_free() which takes place only in the OTG mode. As this commit caused musb_platform_exit() to be called (and so unregister the NOP transceiver) before this put_device() call, this function references already freed memory. On the other hand, all the glue layers miss the otg_put_transceiver() call, complementary to the otg_get_transceiver() call that they do. So, I think the solution is to get rid of the strange put_device() call, and instead call otg_put_transceiver() in the glue layers... Signed-off-by:

Extends FSL EHCI platform driver glue layer to support MPC5121 USB controllers. MPC5121 Rev 2.0 silicon EHCI registers are in big endian format. The appropriate flags are set using the information in the platform data structure. MPC83xx system interface registers are not available on MPC512x, so the access to these registers is isolated in MPC512x case. Furthermore the USB controller clocks must be enabled before 512x register accesses which is done by providing platform specific init callback. The MPC512x internal USB PHY doesn't provide supply voltage. For boards using different power switches allow specifying DRVVBUS and PWR_FAULT signal polarity of the MPC5121 internal PHY using "fsl,invert-drvvbus" and "fsl,invert-pwr-fault" properties in the device tree USB nodes. Adds documentation for this new device tree bindings. Signed-off-by:

Replace FSL USB platform code by simple platform driver for creation of FSL USB platform devices. The driver creates platform devices based on the information from USB nodes in the flat device tree. This is the replacement for old arch fsl_soc usb code removed by this patch. The driver uses usual of-style binding, available EHCI-HCD and UDC drivers can be bound to the created devices. The new of-style driver additionaly instantiates USB OTG platform device, as the appropriate USB OTG driver will be added soon. Signed-off-by:

commit 633ba7876b96ec339ef685357e2f7c60b5a8ce85 broke g_file_storage functionality by enabling AUTOCLEAR on all cases without caring for all gadget drivers. This patch will only enable AUTOCLEAR if our endpoint's FIFO was configured with double buffering support. Note this is not a complete fix, double buffered case still doesn't work always, but that hasn't been working for quite some time. Other than reverting the entire commit and breaking testusb with double buffered case again, I decided it was better to fix the single buffered case and spend more time fixing double buffered case properly.

The USB stack maps the buffer for DMA if the controller supports DMA. MUSB controller can perform DMA as well as PIO transfers. The buffer needs to be unmapped before CPU can perform PIO data transfers. Export unmap_urb_for_dma() so that drivers can perform the DMA unmapping in a sane way. Signed-off-by:

Enabling CONFIG_USB_MUSB_DEBUG option causes -DDEBUG to be added to gcc's command line, however the DBG() macro doesn't depend on DEBUG, so that the debugging messages get printed regardless of the option, and I don't think that this was intended. Get rid of otherwise unused xprintk() macro and make DBG() macro directly call pr_debug() which only results in the actual code generated if DEBUG is defined. This change makes musb_hdrc.o ~30% less in size with CONFIG_USB_MUSB_DEBUG disabled (in host mode). Signed-off-by:

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.

This reverts commit 6a1a82df. 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. Reported-by:

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.
