2006-12-20USB: fix ohci.h over-use warningsJeff Garzik
When u132-hcd is built, it includes local header ohci.h, which appears to have been intended only for use by ohci-hcd. This throws warnings about functions which are defined and not used. The warnings thrown are because three small functions are implemented in the header, but not declared 'inline', a rather strange affair. Since these functions are small, let's go ahead and define them as 'inline', just like the inline functions surrounding them. This makes things more consistent, and kills the warnings.

2006-12-20USB: Prevent the funsoft serial device from entering raw modeDavid Clare
Added a device specific ioctl function to prevent the disabling of canonical mode. EINVAL is returned for any TCSETSF ioctl that doesn't have ICANON set. This patch is for 2.6.17 or later kernels. When "hwinfo --modem" is executed it opens the funsoft USB serial device and disables canonical mode. The device is kept this way until hwininfo has finished probing any modems on a system. The funsoft device expects to be running in canonical mode. Switching the device to raw mode can cause incomplete data packets and device timeouts.

2006-12-01usbcore: remove unused argument in autosuspendAlan Stern
Thanks to several earlier patches, usb_autosuspend_device() and usb_autoresume_device() are never called with a second argument other than 1. This patch (as819) removes the now-redundant argument. It also consolidates some common code between those two routines, putting it into a new subroutine called usb_autopm_do_device(). And it includes a sizable kerneldoc update for the affected functions. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2006-12-01USB: keep count of unsuspended childrenAlan Stern
This patch (as818b) simplifies autosuspend processing by keeping track of the number of unsuspended children of each USB hub. This will permit us to avoid a good deal of unnecessary work all the time; we will no longer have to create a bunch of workqueue entries to carry out autosuspend requests, only to have them fail because one of the hub's children isn't suspended. The basic idea is simple. There already is a usage counter in the usb_device structure for preventing autosuspends. The patch just increments that counter for every unsuspended child. There's only one tricky part: When a device disconnects we need to remember whether it was suspended at the time (leave the counter alone) or not (decrement the counter).

2006-12-01USB hub: simplify remote-wakeup handlingAlan Stern
This patch (as817) simplifies the remote-wakeup processing in the hub driver. Now instead of using a specialized code path, it relies on the standard USB resume routines. The hub_port_resume() function does an initial get_port_status() to see whether the port has already resumed itself (as it does when a remote-wakeup request is sent). This will slow down handling of other resume events slightly, but not enough to matter. The patch also changes the hub_port_status() routine, making it return an error if a short reply is received.

2006-12-01OHCI: make autostop conditional on CONFIG_PMAlan Stern
Unlike UHCI, OHCI does not exert any DMA load on the system when no devices are connected. Consequently there is no advantage to doing an autostop other than the power savings, so we shouldn't compile the necessary code unless CONFIG_PM is enabled. This patch (as820) makes the root-hub suspend and resume routines conditional on CONFIG_PM. It also prevents autostop from activating if the device_may_wakeup flag isn't set; some people use this flag to alert the driver about Resume-Detect bugs in the hardware.

2006-12-01USB: Add autosuspend support to the hub driverAlan Stern
This patch (as742b) adds autosuspend/autoresume support to the USB hub driver. The largest aspect of the change is that we no longer need a special flag for root hubs that want to be resumed. Now every hub is autoresumed whenever khubd needs to access it. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2006-12-01EHCI: Fix root-hub and port suspend/resume problemsAlan Stern
This patch (as738b) fixes numerous problems in the controller/root-hub suspend/resume/remote-wakeup support in ehci-hcd: The bus_resume() routine should wake up only the ports that were suspended by bus_suspend(). Ports that were already suspended should remain that way. The interrupt mask is used to detect loss of power in the bus_resume() routine (if the mask is 0 then power was lost). However bus_suspend() always sets the mask to 0. Instead the mask should retain its normal value, with port-change-detect interrupts disabled if remote wakeup is turned off. The interrupt mask should be reset to its correct value at the end of bus_resume() regardless of whether power was lost. bus_resume() reinitializes the operational registers if power was lost. However those registers are not in the aux power well, hence they can lose their values whenever the controller is put into D3. They should always be reinitialized. When a port-change interrupt occurs and the root hub is suspended, the interrupt handler should request a root-hub resume instead of starting up the controller all by itself. There's no need for the interrupt handler to request a root-hub resume every time a suspended port sends a remote-wakeup request. The pci_resume() method doesn't need to check for connected ports when deciding whether or not to reset the controller. It can make that decision based on whether Vaux power was maintained. Even when the controller does not need to be reset, pci_resume() must undo the effect of pci_suspend() by re-enabling the interrupt mask. If power was lost, pci_resume() must not call ehci_run(). At this point the root hub is still supposed to be suspended, not running. It's enough to rewrite the command register and set the configured_flag.
