This patch adds some simple cleanups that are missing for one of the error case in usb_register_root_hub(). I would be very surprised if this code ever gets executed, but we might as well be correct.

This patch changes the size of the buffer allocated for each hub's status URB from 3 bytes to 8. The purpose is to avoid "babble" errors with certain buggy hubs. Although I only know of one type of device which does this, the patch does solve its problem and it adds no overhead for anyone else since kmalloc doesn't dole out memory in chunks smaller than 8 bytes (32 actually, on a PC). This is a small thing, but it doesn't hurt and it will make life easier for a few people. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <greg@kroah.com>

This patch adds a UDC driver for OMAP, which should work on most OMAP processors. It's been tested most on OMAP 1611/5912. The driver supports all USB transfer types (including ISO), has limited DMA support, and seems to work with all gadget drivers, both to Linux hosts and to MS-Windows ones. One reason this UDC is particularly interesting is that recent OMAP processors all support "USB On-The-Go" (OTG) ... and this driver supports it on at least "H2-like" boards. Another reason is that the UDC is very flexible and fully featured; gadget drivers can allocate fifo space to endpoints in the way that's most convenient for the application.

Greg: This patch updates the part of the usbtest driver that tests URB unlinking. The move to usb_kill_urb() invalidated some of the old tests. There's a corresponding change to the UHCI driver, causing it to return a more descriptive error code in the rare event that an URB is cancelled after it has been linked but before it has been queued.

This adds the isp1301_omap driver, supporting USB OTG on OMAP systems. The driver tightly couples two different chunks of hardware, which are used to implement the OTG protocols: - The Philips ISP1301 OTG transceiver (an I2C device) senses voltage levels and sources VBUS current in the A-Device roles. - OMAP's OTG controller handles lots of OTG transitions, and tells the transceiver what to do. The driver implements the abstract "otg_transceiver" API, since it's got to talk to both the host controller (OHCI on current OMAPs) and the peripheral controller (omap_udc) while hiding a variety of implementation details. It should be easy to tweak to work on other OMAP boards using the isp1301 chip; OMAP boards with other transceivers, or non-OMAP boards using isp1301, will probably find things to learn from. Note that this also supports two non-OTG modes, with the OTG controller disabled; very handy for debugging just the host side USB stack, or just the peripheral side USB stack.

This updates the OMAP OHCI support to match the latest from the Linux-OMAP tree. Notable changes from the preceding version: - Use the new USB init model (arch/arm/mach-omap/usb.c). - The OMAP-specific bus is gone; it now uses platform_device. (Update from Tony Lindgren.) - Works on the H2 board, which requires the external isp1301 transceiver even in non-OTG configurations. - Adds OTG support. - Adds basic power management calls. The mach-omap/Kconfig file in the main Linux tree is a bit out of date, it doesn't know about CONFIG_ARCH_OMAP_OTG (for the OMAPs that have OTG silicon).

Teach usbcore how to enumerate OTG devices and perform HNP: - CONFIG_USB_OTG is a boolean; it selects CONFIG_USB_SUSPEND. Boards with a Mini-AB connector should offer it as a config option; no other hardware could support OTG. - Before resetting a port, make sure it's not still suspended. (For example, after an HNP role switch.) - When an OTG A-Host enumerates a dual-role device, set the appropriate device feature: B_HNP_ENABLE if it's connected to the OTG port, otherwise A_ALT_HNP_SUPPORT. - When an OTG B-Host enumerates a dual-role device, don't bother debouncing ... the power session is stable already, the A-Host already debounced. - The OTG "Targeted Peripheral List" lives in a product-customized "otg_whitelist.h" header. - CONFIG_USB_OTG_WHITELIST lets developers choose to ignore whitelist failures, so unsupported devices can be configured anyway. - If the whitelist check fails, immediately suspend the device. * For dual-role devices, that triggers HNP so the other device can try to act as host. * For peripheral-only devices, that conserves power ... but not quite as much as turning off power on that port, which should eventually be done with OTG ports (and all other ports that support SRP). The whitelist logic tries to make use of the existing usb_device_id logic, but since the interface info isn't available that early it's a bit awkward use information anywhere outside the device descriptor.

Generic OTG and reset support for OTG. - Declare and use a start_hnp() board-specific procedure. The OMAP implementation will come separately, it can't yet be configured. - When OTG is configured, implement the usb_bus_start_enum() hook; that just starts a root port reset. - When some task (usually khubd) resets a root port, make sure it takes the full 50 msec. The OHCI reset timer is in hardware, and the host may need to issue multiple resets to guard against concurrent resume. - For backward compatibility, don't kick in the new 50 msec logic unless it could be needed: without CONFIG_USB_SUSPEND, nothing will suspend so nothing could resume. Which is good, at least until we start to measure how long a reset takes ... it seems chip-specific.

Define a new usb_bus_start_enum() routine that's available with OTG. It starts immediate enumeration (port reset) and makes khubd wake up later. Non-OTG code could start to use this, given some attention to HC-specific reset timing issues.

It turns out that the Konica-Minolta DiMAGE A2 camera, in addition to all its other problems, returns a 0-length reply to the GetMaxLUN request. With this patch (accept a null reply as meaning a single LUN) it is somewhat useable. It's amazing to me that vendors have this much trouble counting to 1....

This patch has been hanging around for a while and seems to have been forgotten. It fixes a bug in the USB scatter-gather library that crops up when submission of an URB fails, and it fixes a bug in the cleanup routine when some of the URBs being cleaned up have already completed.

Don't clear ep0 status phase handshake during endpoint reset ... at least one driver emits so much debug output before resetting endpoints that the reset happens late enough to make the chip break protocol. Also handle resets IRQs a bit differently: they can happen twice during enumeration, which can worsen the other problem.

This patch fixes the error in the UHCI driver found by Stuart Hayes. It adds the UHCI_PTR_QH bit into the initial entries stored in the hardware framelist. It's not entirely clear how the driver ever managed to work with these bits not set; apparently by coincidence the QH entries resembled TD entries sufficiently closely to fool the hardware.

On some platforms (notably power5) you can't enable surveillance (firmware/service processor watchdog) from the kernel - you have to do it in the firmware. This patch changes enable_surveillance() to make the message that is printed in this situation more informative. Additionaly, the rtas_call was changed to rtas_set_indicator so as to avoid having to handle RTAS_BUSY returns.

The code doesn't actually _care_ about 32/64-bit issues, only about F_SETLK vs F_SETLKW, and the F_SETLK64 doesn't exist except as a compatibility thing on 64-bit architectures (since the regular one already _is_ 64-bit, of course).
