2008-05-14USB: atmel_usba_udc fixes, mostly disconnect()David Brownell
Various fixes to Atmel's high speed UDC driver. * Issue some missing disconnect() calls. Currently they are only made when VBUS power goes away (on boards where the driver can sense such changes), but that's not enough for gadget drivers to clean out all the state that's needed. Missing calls were: - After USB reset, before starting enumeration. - When unregistering a gadget driver, before unbind(). * Don't assume gadget drivers provide disconnect callbacks; make sure to not call through a null pointer! * When the driver doesn't provide an unbind() callback, refuse to unregister it. Also remove two bogus "error" messages: * Related to mis-handling of disconnect() ... don't emit error messages for disconnect() handlers that disable endpoints. All of them should be doing that; the problem is (unfixed) oddness in atmel_usba_udc. * Don't emit a diagnostic for a curious and transient nonfatal error that shows up sometimes with EP0. Those messages spammed syslog, for no good reason.

2008-05-14USB: remove PICDEM FS USB demo (04d8:000c) device from ldusbXiaofan Chen
Microchip has changed the PICDEM FS USB demo device (0x04d8:000c) to use bulk transfer and not interrupt transfer. So I've updated the libusb based program here (Post #31). http://forum.microchip.com/tm.aspx?m=106426&mpage=2 So I believe that the in-kernel ldusb driver will no longer work with the demo firmware.

Enables the SD-Card interface on the GI 0401 HSUPA card from Option. The unusual_devs.h entry is necessary because the device descriptor is vendor-specific. That prevents usb-storage from binding to it as an interface driver. This revised patch adds a small comment explaining why and reduces the rev range.

2008-05-14USB: serial gadget: descriptor cleanupDavid Brownell
Bugfix some serial gadget descriptors: - Stop mangling the low bits (controller type ID) of bcdDevice; just use the high bits for a driver revision code. - Serial numbers that aren't specific to individual devices are useless; stop reporting "0" for this. - Since it's not part of a CDC-conformant function, the "bulk only" configuration shouldn't be using "CDC Data" as its interface class.

2008-05-14USB: serial gadget: remove needless data structureDavid Brownell
This removes a needless data structure from the serial gadget code; it's a small code shrink, and a larger data shrink. Since "struct usb_request" already has a "struct list_head" reserved for use by gadget drivers, the serial gadget code doesn't need to allocate wrapper structs to hold that list ... it can (and should!) just use the list_head provided for that exact use.

2008-05-14USB: serial gadget: cleanup/reorgDavid Brownell
Some cleanup/reorg of g_serial ... simplifying it, and disentangling its structure so morphing it into a "function" driver (combinable with other interfaces) should be less painful. - Remove most forward declarations * put tty and gadget driver structs after their contents * snug module init/exit decls next to their functions * reordered some functions - Other cleanup: * convert a funky macro to an inline function * snug up module params next to their declarations * add missing driver.owner * add separator lines between major driver sections - Add comments re potential parameter/#define changes: * only supports one port (shrank GS_NUM_PORTS) * changing from 9600-8-N-1 affects multiple sites - Remove net2280-specific optimization ... it was being done way too late, can be done by net2280 module options, and in any case doesn't matter at any sane serial data rates. There are no behavioral changes, but the macro thing saves I-space.

This patch (as1087d) fixes a long-standing problem in usbcore: Device, interface, and endpoint attributes aren't added until _after_ the creation uevent has already been broadcast. Unfortunately there are a few attributes which cannot be created that early. The "descriptors" attribute is binary and so must be created separately. The power-management attributes can't be created until the dev/power/ group exists. And the interface string can vary from one altsetting to another, so it has to be created dynamically.

2008-05-13[SCSI] qla1280: Fix queue depth problemJeremy Higdon
The qla1280 driver was ANDing the output value of mailbox register 0 with (1 << target-number) to determine whether to enable queueing on the target in question. But mailbox register 0 has the status code for the mailbox command (in this case, Set Target Parameters). Potential values are: /* * ISP mailbox command complete status codes */ So clearly that is in error. I can't think what the author of that line was looking for in a mailbox register, so I just eliminated the AND. flag is used later in the function, and I think that the later usage was also wrong, though it was used to set values that aren't used. Oh well, an overhaul of this driver is not what I want to do now -- just a bugfix. After the fix, I found that my disks were getting a queue depth of 255, which is far too many. Most SCSI disks are limited to 32 or 64. In any case, there's no point, queueing up a bunch of commands to the adapter that will just result in queue full or starve other targets from being issued commands due to running out of internal memory. So I dropped default queue depth to 32 (from which 1 is subtracted elsewhere, giving net of 31). I tested with a Seagate ST336753LC, and results look good, so I'm satisfied with this patch.

2008-05-13PCI: enable nv_msi_ht_cap_quirk for ALi bridgesBjörn Krombholz
This applies the NVidia MSI enabled flag for HT capable devices quirk to ALi bridges as well. As described in more detail in http://bugzilla.kernel.org/show_bug.cgi?id=10667 this is required for my board which is using an nForce 3 250Gb chipset with an ALi M1695 northbridge. It fixes a regression introduced in 2.6.24 that made the internal NIC of the board unusable (MSI initialisation of the NIC but disabled MSI on the northbridge devices.

2008-05-13PCI: Make the intel-iommu_wait_op macro work when jiffies are not runningmark gross
The following patch changes the intel-iommu.c code to use the TSC instead of jiffies for detecting bad DMAR functionality. Some systems with bad bios's have been seen to hang in early boot spinning in the IOMMU_WAIT_IO macro. This patch will replace the infinite loop with a call to panic.

2008-05-13ACPI/PCI: handle multiple _OSCKenji Kaneshige
The pci_osc_control_set() function can be called for the ACPI object that doesn't have _OSC method. In this case, acpi_get_osc_data() would allocate a useless memory region. To avoid this, we need to check the existence of _OSC before calling acpi_get_osc_data(). Here is a patch to fix this problem in pci_osc_control_set.

There is an IA64 system here which have two pci root bridges with _OSC. One _OSC disables SHPC control bit but the other not. Below patch makes _OSC data per-device instead of one global, otherwise linux takes both root bridges don't support SHPC.

2008-05-13PCI ACPI: fix uninitialized variable in __pci_osc_support_setKenji Kaneshige
Fix uninitialized variable in __pci_osc_support_set(). If the ACPI namespace doesn't have any device object corresponding to the specified hid, 'retval' in __pci_osc_support_set() is not changed by the acpi_query_osc() callback. Since 'retval' is not initizlized in the current implementation, the contents of 'retval' is undefined in this case. This causes a mis-handling of ctrlset_buf[OSC_SUPPORT_TYPE] and will cause an unexpected result in the subsequent pci_osc_control_set() call as a result.

2008-05-13vt/fbcon: fix background color on line feedJan Engelhardt
Another addendum to commit c9e587abfdec2c2aaa55fab83bcb4972e2f84f9b ("vt: fix background color on line feed"). fbcon still was not doing the right thing (read: continued to do old behavior). fbcon_clear() seems to clear the new line (e.g. where your new prompt appears after doing echo -en "\e[42mfoo\n"), while scr_memsetw clears the previous one only (where "foo" appears). So just temporarily set the video_erase_char to the scrl_erase_char so that fbcon_clear does the right thing.

2008-05-13spi_mpc83xx: much improved driverJoakim Tjernlund
The current driver may cause glitches on SPI CLK line since one must disable the SPI controller before changing any HW settings. Fix this by implementing a local spi_transfer function that won't change speed and/or word size while CS is active. While doing that heavy lifting a few other issues were addressed too: - Make word size 16 and 32 work too. - Honor bits_per_word and speed_hz in spi transaction. - Optimize the common path. This also stops using the "bitbang" framework (except for a few constants).
