CPU/board specific parameters (PLL clock, vif etc...) can be set by platform_data instead of module_param. v2: remove irq_sense member in platform_data because it can OR in IRQF_TRIGGER_LOW or IRQF_TRIGGER_FALLING against IORESOURCE_IRQ in the struct resource.

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).

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. Signed-off-by:

Omap3 MUSB AUTOIDLE functionality configured through OTG_SYSCONFIG register prevents the device from going into retention. This is a workaround (by Richard Woodruff/TI), as his comment : > A new MUSB bug which is a match to data below was identified very > recently (on hardware and in simulation). > This bug is in 3430 and not 3630. > As a priority test (and as new default) you should have engineers > disable autoidle for MUSB block. > This is the workaround which will show up in next errata.

The endpoint devices look like simple attribute groups now, and no longer like devices with a specific subsystem. They will also no longer emit uevents. It also removes the device node requests for endpoint devices, which are not implemented for now. Signed-off-by:

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: -

Alan Stern commented that the private driver counts must be updated regard less of the status return on the urb when the write call back is executed. This patch alters the behavior to update the private driver counts by simply moving the status check to after the driver count update. Signed-off-by:

Jason Wessel authored
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. Signed-off-by:

This patch fixes a problem in function sierra_indat_callback() which would stop receiving traffic from a modem if a number of URB failures occur. Failed URBs are not resubmitted for the next read and there is only a limited number of URBs allocated for the IN path. After this number of failures, the receive path stops working on a particular interface. Signed-off-by: -

We all know that pointless janitoring is bad, but this code is just offensive. So: - The error code goes directly to probe return, so don't return -1. - Don't return return internal usb-storage codes either. - usb_stor_control_msg takes timeout in milliseconds. - Sanitize messages. Signed-off-by:

This patch (as1237) changes the way the PCI host controller drivers avoid retaining bogus hardware states during resume-from-hibernation. 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:

Right now we jump through some hoops to get to the struct ohci_hcd struct in the ohci debugfs files. Remove all of the fun casting around and just use the pointer directly. 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: -

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. Signed-off-by:

utf8_wcstombs forgot to include one-byte UTF-8 characters when calculating the output buffer size, i.e., theoretically, it was possible to overflow the output buffer with an input string that contains enough ASCII characters. In practice, this was no problem because the only user so far (VFAT) always uses a big enough output buffer. Signed-off-by:

Clemens Ladisch authored
When utf8_wcstombs encounters a character that cannot be encoded, we must not decrease the remaining output buffer size because nothing has been written to the output buffer. Signed-off-by:

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.
