* USB: usb-serial: replace shutdown with disconnect, releaseAlan Stern2009-06-1535-192/+287
| | | | | | | | | | | | | | | | This patch (as1254) splits up the shutdown method of usb_serial_driver into a disconnect and a release method. The problem is that the usb-serial core was calling shutdown during disconnect handling, but drivers didn't expect it to be called until after all the open file references had been closed. The result was an oops when the close method tried to use memory that had been deallocated by shutdown.

* USB: usb-serial: call port_probe and port_remove at the right timesAlan Stern2009-06-152-18/+33
| | | | | | | | | | | This patch (as1253) prevents the usb-serial core from calling a driver's port_probe and port_remove methods more than once per port. It also removes some unnecessary try_module_get() calls and adds a missing port_remove method call in a failure path.

* USB: gadget: Add i.MX3x support to the fsl_usb2_udc driverGuennadi Liakhovetski2009-06-155-24/+164
| | | | | | | | | | | | | | This patch adds support for i.MX3x (only tested with i.MX31 so far) ARM SoCs to the fsl_usb2_udc driver. It also moves PHY configuration before controller reset, because otherwise an ULPI PHY doesn't get a reset and doesn't function after a reboot. The problem with longer control transfers is still not fixed. The patch renames the fsl_usb2_udc.c file to fsl_udc_core.c to preserve the same module name for user-space backwards compatibility.

* USB: usb_serial: only allow sysrq on a console portJason Wessel2009-06-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | The only time a sysrq should get processed is if the attached device is a console. This is intended to protect sysrq execution on a host connected with a terminal program. Here is the problem scenario: host A <-- rs232 link --> host B Host A is using mincom and a usb pl2303 device to connect to host b which is a linux system with a usb pl2303 device acting as the serial console. When host B is rebooted the pl2303 emits random junk characters on reset. These character sequences contain serial break signals most of the time and when translated to a sysrq have caused host A to get random processes killed, reboots or power down. It is true that in this setup with this patch host B might still have the same problem as host A if you reboot host A. In most cases host A is a development host which seldom gets rebooted, and you could turn off sysrq temporarily on host B if you need to reboot host A.

| | | | | | | | | | | | | | | | | When a zero-length packet has been requested and another packet is written into the fifo, the MX1 tends to send the first byte of the previous packet instead of the first byte of the current packet. The CRC is adjusted accordingly so that this packet is _not_ discarded by the host. Waiting for the ZLPS bit to clear avoids these bad packets.

* USB: EHCI: update toggle state for linked QHsAlan Stern2009-06-159-18/+53
| | | | | | | | | | | | | | | | | | | | | | | | | This patch (as1245) fixes a bug in ehci-hcd. When an URB is queued for an endpoint whose QH is already in the LINKED state, the QH doesn't get refreshed. As a result, if usb_clear_halt() was called during the time that the QH was linked but idle, the data toggle value in the QH doesn't get reset. The symptom is that after a clear_halt, data gets lost and transfers time out. This problem is starting to show up now because the "ehci-hcd unlink speedups" patch causes QHs with no queued URBs to remain linked for a suitable time. The patch utilizes the new endpoint_reset mechanism to fix the problem. When an endpoint is reset, the new method forcibly unlinks the QH (if necessary) and safely updates the toggle value. This allows qh_update() to be simplified and avoids using usb_device's toggle bits in a rather unintuitive way.

| | | | | | | | | | | | | | | | | | | | | | Some unusual usb devices from the maker "Option" are switched from storage to serial/modem mode by sending a SCSI REZERO command. In one case a fairly common vendor/device ID is affected which led to problems for users of other modems or phones which are not supposed to be switched. The patch adds a filter by reading the vendor name with the SCSI INQUIRY command, and skips the switching code for all unrecognized entries. Further changes are cleanups and corrections pointed out by Alan Stern. Tested with two devices with the IDs 05c6:1000, one from "Option" and switchable, and one from Samsung (cell phone).

* USB: EHCI: stagger frames for interrupt transfersAlan Stern2009-06-152-3/+6
| | | | | | | | | | | | | | | | | | This patch (as1243) tries to improve ehci-hcd's scheduling of interrupt transfers. Instead of trying to cram all transfers with the same period into the same frame, the new code will spread the transfers out among lots of different frames. This should reduce the periodic schedule load in any one frame -- some host controllers have trouble when there's too much work to do. A more thorough approach would stagger the uframe values as well. But this is enough to make a big improvement.

| | | | | | | | | | | | | | | | | | | | | | | | | | | The usb_debug driver was modified to implement serial break handling by using a "magic" data packet comprised of the sequence: 0x00 0xff 0x01 0xfe 0x00 0xfe 0x01 0xff When the tty layer requests a serial break the usb_debug driver sends the magic packet. On the receiving side the magic packet is thrown away or a sysrq is activated depending on what kernel .config options have been set. The generic serial driver was modified as well as the usb serial headers to generically implement sysrq processing in the same way the non usb uart based drivers implement the sysrq handling. This will allow other usb serial devices to implement sysrq handling as desired. The new usb serial functions are named similarly and implemented similarly to the uart functions as follows: usb_serial_handle_break <-> uart_handle_break usb_serial_handle_sysrq_char <-> uart_handle_sysrq_char Signed-off-by: Jason Wessel <jason.wessel@windriver.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* USB: usb_debug, usb_generic_serial: implement multi urb writeJason Wessel2009-06-152-7/+116
| | | | | | | | | | | | | | | | | | | | | | | | | | The usb_debug driver, when used as the console, will always fail to insert the carriage return and new line sequence as well as randomly drop console output. This is a result of only having the single write_urb and that the tty layer will have a lock that prevents the processing of the back to back urb requests. The solution is to allow more than one urb to be outstanding and have a slightly deeper transmit queue. The idea and some code is borrowed from the ftdi_sio usb driver. The generic usb serial driver was modified so as to allow the classic method of 1 write urb, or a multi write urb scheme with N allowed outstanding urbs where N is controlled by max_in_flight_urbs. When max_in_flight_urbs in a "struct usb_serial_driver" is non zero the multi write urb scheme will be used. The size of 4000 was selected for the usb_debug driver so that the driver lowers possibility of losing the queued console messages during the kernel startup.

Previously we had reset the hardware as part of preparing to reinstate the memory image. But we can do better now with the new PM framework, since we know exactly which resume operations are from hibernation. The pci_resume method is changed to accept a flag indicating whether the system is resuming from hibernation. When this flag is set, the drivers will reset the hardware to get rid of any existing state. Similarly, the pci_suspend method is changed to remove the pm_message_t argument. It's no longer needed, since no special action has to be taken when preparing to reinstate the memory image. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Acked-by: Rafael J.

This is needed as the dev pointer in the hcd structure is going away, and it makes the code simpler and smaller Cc: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* NLS: update handling of UnicodeAlan Stern2009-06-151-7/+3
| | | | | | | | | | | | | | | | | | | | | | | | | This patch (as1239) updates the kernel's treatment of Unicode. The character-set conversion routines are well behind the current state of the Unicode specification: They don't recognize the existence of code points beyond plane 0 or of surrogate pairs in the UTF-16 encoding. The old wchar_t 16-bit type is retained because it's still used in lots of places. This shouldn't cause any new problems; if a conversion now results in an invalid 16-bit code then before it must have yielded an undefined code. Difficult-to-read names like "utf_mbstowcs" are replaced with more transparent names like "utf8s_to_utf16s" and the ordering of the parameters is rationalized (buffer lengths come immediate after the pointers they refer to, and the inputs precede the outputs). Fortunately the low-level conversion routines are used in only a few places; the interfaces to the higher-level uni2char and char2uni methods have been left unchanged.

* USB: add the usbfs devices file to debugfsGreg Kroah-Hartman2009-06-152-2/+15
| | | | | | | | | | | People are very used to the devices file in usbfs. Now that we have moved usbfs to be an "embedded" option only, the developers miss the file, they had grown quite attached to it over all of these years. This patch brings it back and puts it in the usb debugfs directory, so that the developers don't feel sad anymore. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
