2010-08-10USB: gadget: g_mass_storage: static data instead of dynamic allocationMichal Nazarewicz1-6/+9
This patch changes msg_do_config() function so that it uses a static object for a fsg_common structure instead of dynamically allocated. This is a micro-optimisation.

2010-08-10USB: mon: kill BKL usageArnd Bergmann1-20/+2
compat_ioctl does not use the BKL, so I assume that the native function does not need it either. The open function is already protected by the driver's mutex, the BKL is probably not needed here either.

2010-08-10usb: gadget: Do not take BKL for gadget->ops->ioctlArnd Bergmann2-6/+2

BKL was not really needed, just came from earlier push downs. The only part that's a bit dodgy is the lseek function. Would need another lock or atomic access to fpos on 32bit?

2010-08-10USB-BKL: Remove BKL use for usb serial driver probingAndi Kleen1-16/+14
The usb serial driver initialization tried to use the BKL to stop driver modules from unloading, but that didn't work anyways. There was already some code to do proper try_module_get, but it was conditional on having a new probe interface. I checked all the low level drivers and they all have proper .owner = THIS_MODULE, so it's ok to always use. The other problem was the usb_serial_driver_list needing protection by a lock. This was broken anyways because unregister did not necessarily have the BKL. I extended the extending table_lock mutex to protect this case too. With these changes the BKL can be removed here.

The code this is attempting to lock against does not use the BKL, so it's not needed.

2010-08-10USB: EHCI: make CONFIG_USB_EHCI_TT_NEWSCHED default to YAlan Stern1-4/+7
This patch (as1382) changes the USB_EHCI_TT_NEWSCHED Kconfig option to be non-experimental and to default to Y. This option has existed for a long time, and I have not heard any complaints concerning it. By contrast, several people have reported that their devices could be made to work only by enabling the option. The point of changing the default is to cause the option to be enabled by distros that simply use the default settings for esoteric things like this. This change was motivated by Bugzilla #15649.

2010-08-10USB: UHCI: acquire spinlock before calling start_rh()Alan Stern2-2/+4
This patch (as1392) fixes a bug in uhci-hcd: The start_rh() routine is supposed to be called with the private spinlock held. If an IRQ comes in at just the wrong time, the driver will think the controller has died when in fact it simply hasn't start yet. The patch also addresses some issues that may prevent an URB from being unlinked after the controller has stopped. This is an abnormal occurrence (ordinarily the controller stops only when the entire bus is suspended and hence there are no active URBs), so the pathways haven't gotten much testing. These two changes may be a little more than is strictly necessary, but clearly they won't hurt. Signed-off-by: Alan Stern <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]>
2010-08-10USB: add check to detect host controller hardware removalAlan Stern1-0/+8
This patch (as1391) fixes a problem that can occur when USB host controller hardware is hot-unplugged. If no interrupts are generated by the unplug then the HCD may not realize that the controller is gone, and the subsequent unbind may hang waiting for interrupts that never arrive. The solution (for PCI-based controllers) is to call the HCD's interrupt handler at the start of usb_hcd_pci_remove(). If the hardware is gone, the handler will realize this when it tries to read the controller's status register.

2010-08-10USB: don't stop root-hub status polls too soonAlan Stern2-7/+26
This patch (as1390) fixes a problem that crops up when a UHCI host controller is unbound from uhci-hcd while there are still some active URBs. The URBs have to be unlinked when the root hub is unregistered, and uhci-hcd relies upon root-hub status polls as part of its unlinking procedure. But usb_hcd_poll_rh_status() won't make those status calls if hcd->rh_registered is clear, and the flag is cleared _before_ the unregistration takes place. Since hcd->rh_registered is used for other things and needs to be cleared early, the solution is to add a new flag (rh_pollable) and use it instead. It gets cleared _after_ the root hub is unregistered. Now that the status polls don't end too soon, we have to make sure they also don't occur too late -- after the root hub's usb_device structure or the HCD's private structures are deallocated. Therefore the patch adds usb_get_device() and usb_put_device() calls to protect the root hub structure, and it adds an extra del_timer_sync() to prevent the root-hub timer from causing an unexpected status poll. This additional complexity would not be needed if the HCD framework had provided separate stop() and release() callbacks instead of just stop(). This lack could be fixed at some future time (although it would require changes to every host controller driver); when that happens this patch won't be needed any more.

2010-08-10USB: fix failure path in usb_add_hcd()Alan Stern1-2/+16
This patch (as1389) fixes some errors in the failure pathway of usb_add_hcd(). The actions it takes ought to be exactly the same as those taken by usb_remove_hcd(), but they aren't. In one case (removal of the usb_bus_attr_group), the two routines are brought into agreement by changing usb_remove_hcd(). All the other discrepancies are fixed by changing usb_add_hcd().

2010-08-10hsu: add a periodic timer to check dma rx channelFeng Tang1-3/+47
A general problem for uart rx dma channel is you never know when and how much data will be received, so usually preset it a DMA descriptor with a big size, and rely on DMA RX timeout IRQ to know there is some data in rx channel. For a RX data size of multiple of MOTSR, there will be no timeout IRQ issued, thus OS will never be notified about that. This is a work around for that, current timer frequency is 5 times per second, it should vary according to the baud rate When future silicon version fix the problem, this workaround need be removed Signed-off-by: Feng Tang <[email protected]> Signed-off-by: Alan Cox <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]>
2010-08-10hsu: driver for Medfield High Speed UART deviceFeng Tang6-0/+1564
This is a PCI & UART driver, which suppors both PIO and DMA mode UART operation. It has 3 identical UART ports and one internal DMA controller. Current FW will export 4 pci devices for hsu: 3 uart ports and 1 dma controller, each has one IRQ line. And we need to discuss the device model, one PCI device covering whole HSU should be a better model, but there is a problem of how to export the 4 IRQs info Current driver set the highest baud rate to 2746800bps, which is easy to scale down to 115200/230400.... To suport higher baud rate, we need add special process, change DLAB/DLH/PS/DIV/MUL registers all together. 921600 is the highest baud rate that has been tested with Bluetooth modem connected to HSU port 0. Will test more when there is right BT firmware.
