2005-06-27[PATCH] USB: ethernet gadget updates (mostly cleanup)David Brownell
Some cleanup for the the Ethernet part of the Ethernet/RNDIS gadget driver: - Remove remnants of ancient endpoint init logic; this is simpler, clearer - Save a smidgeon of space in the object file - Get rid of some #ifdeffery, mostly by using some newish inlines - Reset more driver state as part of USB reset - Remove a needless wrapper around an RNDIS call - Improve and comment the status interrupt handling: * RNDIS sometimes needs to queue these transfers (rarely in normal cases, but reproducibly while Windows was deadlocking its USB stack) * Mark requests as busy/not - Enable the SET_NETDEV_DEV() call; sysfs seems to behave sanely now This is a net shrink of source code.

2005-06-27[PATCH] USB: rndis updates (mostly cleanup)David Brownell
Some bugfixes and lots of cleanup (net code shrink): - On reset, force the RNDIS state machine its initial state - Hook up the RNDIS (outgoing) filters to the CDC mechanism - Lots of cleanup: * Eliminate duplicate copy of OID table; * Unify handlying of the OID "query" response data pointer; * Reduce code duplication for calculating query response lengths; * Remove some checks for "can't happen" errors; * Get rid of debugging #ifdefs by making the debug flag an integer level Most of the patch, by volume, relates to those query response cleanups. It incidentally shaves off a few hundred bytes of object code. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2005-06-27[PATCH] USB HCDs: no longer need to register root hubAlan Stern

2005-06-27[PATCH] usbcore: register root hub in usb_add_hcdAlan Stern
This patch makes usbcore automatically allocate and register the root hub device for a new host controller when the controller is registered. This way the HCDs don't all have to include the same boilerplate code. As a pleasant side benefit, the register_root_hub routine can now be made static and not EXPORTed.

2005-06-27[PATCH] UHCI: Don't store device pointer in QH or TDAlan Stern
This patch simplifies the uhci-hcd driver by removing the device pointer currently stored in the QH and TD structures. Those pointers weren't being used for anything other than to increment the device's reference count, which is unnecessary since the device is used only when an URB completes, and outstanding URBs take their own reference to the device. As a useful side effect, this change means that uhci-hcd no longer needs to have the root-hub device available in the start routine.

2005-06-27[PATCH] usbcore: Remove hub_set_power_budgetAlan Stern
This patch removes the hub_set_power_budget routine, which was used by a couple of HCDs to indicate that the root hub was running on battery power. In its place is a new field added to struct usb_hcd, which HCDs can set before the root hub is registered. Special-case code in the hub driver knows to look at this field when configuring a root hub.

This patch enables power management (suspend, resume) support for zd1201.

2005-06-27[PATCH] usbcore support for root-hub IRQ instead of pollingAlan Stern
This is a revised version of an earlier patch to add support to usbcore for driving root hubs by interrupts rather than polling. There's a temporary flag added to struct usb_hcd, marking devices whose drivers are aware of the new mechanism. By default that flag doesn't get set so drivers will continue to see the same polling behavior as before. This way we can convert the HCDs one by one to use interrupt-based event reporting, and the temporary flag can be removed when they're all done. Also included is a small change to the hcd_disable_endpoint routine. Although endpoints normally shouldn't be disabled while a controller is suspended, it's legal to do so when the controller's driver is being rmmod'ed. Lastly the patch adds a new callback, .hub_irq_enable, for use by HCDs where the root hub's port-change interrupts are level-triggered rather than edge-triggered. The callback is invoked each time khubd has finished processing a root hub, to let the HCD know that the interrupt can safely be re-enabled.

2005-06-27[PATCH] USB UHCI: Add shutdown methodAlan Stern
After all the discussion you might not be interested in this still, but nevertheless here it is. This patch adds a shutdown method to the uhci-hcd driver. Its prerequisite is the patch you wrote adding shutdown support for PCI. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2005-06-27[PATCH] USB UHCI: improved reset handlingAlan Stern
This patch improves the strategy uhci-hcd uses for performing controller resets and checking whether they are needed. The HCRESET command doesn't affect the Suspend, Resume, or Reset bits in the port status & control registers, so the driver must clear them by itself. This means the code to figure out how many ports there are has to be moved to an earlier spot in the driver. The R/WC bits in the USBLEGSUP register can be set by the hardware even in the absence of BIOS meddling with legacy support features. Hence it's not a good idea to check them while trying to determine whether the BIOS has altered the controller's state.

2005-06-27[PATCH] USB UHCI: Use root-hub IRQs while suspendedAlan Stern
This patch, which has as478b as a prerequisite, enables the uhci-hcd driver to take advantage of root-hub IRQs rather than polling during the time it is suspended. (Unfortunately the hardware doesn't support port-change interrupts while the controller is running.) It also turns off the driver's private timer while the controller is suspended, as it isn't needed then. The combined elimination of polling interrupts and timer interrupts ought to be enough to allow some systems to save a noticeable amount of power while they are otherwise idle.

2005-06-27[PATCH] USB UHCI: Fix up loose endsAlan Stern
This patch tidies up a few loose ends left by the preceding patches. It indicates the controller supports remote wakeup whenever the PM capability is present -- which shouldn't cause any harm if the assumption turns out to be wrong. It refuses to suspend the controller if the root hub is still active, and it refuses to resume the root hub if the controller is suspended. It adds checks for a dead controller in several spots, and it adds memory barriers as needed to insure that I/O operations are completed before moving on. Actually I'm not certain the last part is being done correctly. With code like this: outw(..., ...); mb(); udelay(5); do we know for certain that the outw() will complete _before_ the delay begins? If not, how should this be written? Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2005-06-27[PATCH] USB UHCI: Add root-hub suspend/resume supportAlan Stern
This patch implements (finally!) separate suspend and resume routines for the root hub and the controller in the UHCI driver. It also changes the sequence used to reset the controller during initial probing, so as to preserve the existing state during a Resume-From-Disk. (This new sequence is what should be used in the PCI Quirks code for early USB handoffs, incidentally.) Lastly it adds a notion of the controller being "inaccessible" while in a PCI low-power state, when normal I/O operations shouldn't be allowed.

2005-06-27[PATCH] USB UHCI: Add root hub statesAlan Stern
This patch starts making some serious changes to the UHCI driver. There's a set of private states for the root hub, and the internal routines for suspending and resuming work completely differently, with transitions based on the new states. Now the driver distinguishes between a privately auto-stopped state and a publicly suspended state, and it will properly suspend controllers with broken resume-detect interrupts instead of resetting them.

2005-06-27[PATCH] USB: turn a user mode driver error into a hard errorDavid Brownell
This patch turns a user mode driver error into a hard error, and updates the relevant diagnostic slightly to help troubleshooting. gphoto was known to have this problem, hopefully it is now fixed (they have had plenty of warning...) This had been left as a soft error to give various user mode drivers a change to be properly fixed, with the statement that starting in about 2.6.10 it would be changed. It had been mostly safe as a soft error ... but that can not be guaranteed. Now that a year has passed, it's time to really insist that the user mode drivers finally fix their relevant bugs.

2005-06-27[PATCH] USB: Fix oops at rmmod after failed probe in isp116x-hcdOlav Kongas
This patch fixes an oops triggered at rmmod of isp116x-hcd after the probe() has failed. Also, it extends the error message printed, if the driver cannot detect "Chip's Clock Ready" after a software reset. As Ian Campbell recently reported, this happens if the chip's H_WAKEUP pin is not pulled low during software reset. Several people have already had this issue, hence the update to the error message. Also, extend the error message about the failed clock detection after the software reset. Signed-off-by: Olav Kongas <ok@artecdesign.ee>

This patch provides an "isp116x-hcd" driver for Philips' ISP1160/ISP1161 USB host controllers. The driver: - is relatively small, meant for use on embedded platforms. - runs usbtests 1-14 without problems for days. - has been in use by 6-7 different people on ARM and PPC platforms, running a range of devices including USB hubs. - supports suspend/resume of both the platform device and the root hub; supports remote wakeup of the root hub (but NOT the platform device) by USB devices. - does NOT support ISO transfers (nobody has asked for them). - is PIO-only.

2005-06-27[PATCH] USB: omap_udc updates (mostly cleanups)David Brownell
Various USB patches, mostly for portability: - Fifo mode 1 didn't work previously (oopsed), so now it's fixed and (why not) defines even more endpoints for composite devices. - OMAP 1710 doesn't have an internal transceiver. - Small PM update: if the USB link is suspended, don't disconnect on entry to deep sleep. - Be more correct about handling zero length control reads. OMAP seems to mis-handle that protocol peculiarity though; best avoided. - Platform device resources (for UDC and OTG controllers) now use physical addresses, so /proc/iomem is more consistent. - Minor cleanups, notably (by volume) for "sparse" NULL warnings.

Remove the argument that is no longer necessary from two function calls. 5. Some whitespace cleanup 6. Clear potential race in refrigerator (provides an open window of PF_FREEZE cleared before setting PF_FROZEN, recalc_sigpending does not check PF_FROZEN). This patch does not address the problem of freeze_processes() violating the rule that a task may only modify its own flags by setting PF_FREEZE.

2005-06-20[PATCH] usb: klist_node_attached() fixPatrick Mochel
The original code looks like this: /* if interface was already added, bind now; else let * the future device_add() bind it, bypassing probe() */ if (!list_empty (&dev->bus_list)) device_bind_driver(dev); IOW, it's checking to see if the device is attached to the bus or not and binding the driver if it is. It's checking the device's bus list, which will only appear empty when the device has been initialized, but not added. It depends way too much on the driver model internals, but it seems to be the only way to do the weird crap they want to do with interfaces. When I converted it to use klists, I accidentally inverted the logic, which led to bad things happening. This patch returns the check to its orginal value.
