2010-08-10USB: UHCI: acquire spinlock before calling start_rh()Alan Stern
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.

2010-08-10USB: add check to detect host controller hardware removalAlan Stern
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 Stern
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 Stern
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().

This fixes a regression due to the new apb_pclk stuff in the U300 platform, makes it run by splitting the apb clock off the single UART clocks. For the MMCI and PL022 clocks we don't split them: these are actually hardwired to the same clock terminal and will thus simply have a double reference count and will be referenced twice. We also move clock registration to .init_irq() so they are available early enough for probing to be successful and remove the earlier quirk to clock primecells during PrimeCell registration.

2010-08-10hsu: add a periodic timer to check dma rx channelFeng Tang
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 <feng.tang@intel.com> Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2010-08-10hsu: driver for Medfield High Speed UART deviceFeng Tang
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.

2010-08-10serial: fix missing bit coverage of ASYNC_FLAGSJohn Villalovos
It seems that currently ASYNC_FLAGS is one bit short of covering all the bits of the ASYNC user flags. In particular it does not cover the ASYNC_AUTOPROBE bit. ASYNCB_LAST_USER and ASYNCB_AUTOPROBE are both equal to 15. Therefore: ASYNC_AUTOPROBE = 1000 0000 0000 0000 ASYNC_FLAGS = 0111 1111 1111 1111 So ASYNC_FLAGS is not covering the ASYNC_AUTOPROBE bit. This patch fixes the issue and with the patch the values will be: ASYNC_AUTOPROBE = 1000 0000 0000 0000 ASYNC_FLAGS = 1111 1111 1111 1111 As a side note, doing a "git grep" I didn't find any use of ASYNC_AUTOPROBE or ASYNCB_AUTOPROBE in the kernel, besides this include file.

Using: gcc (GCC) 4.5.0 20100610 (prerelease) with CONFIG_CONSOLE_TRANSLATIONS=n, the following warnings are seen: drivers/char/vt_ioctl.c: In function ‘vt_ioctl’: drivers/char/vt_ioctl.c:1309:4: warning: statement with no effect drivers/char/vt.c: In function ‘vc_allocate’: drivers/char/vt.c:774:3: warning: statement with no effect drivers/video/console/vgacon.c: In function ‘vgacon_init’: drivers/video/console/vgacon.c:587:3: warning: statement with no effect drivers/video/console/vgacon.c: In function ‘vgacon_deinit’: drivers/video/console/vgacon.c:606:2: warning: statement with no effect drivers/video/console/fbcon.c: In function ‘fbcon_init’: drivers/video/console/fbcon.c:1087:3: warning: statement with no effect drivers/video/console/fbcon.c:1089:3: warning: statement with no effect drivers/video/console/fbcon.c: In function ‘fbcon_set_disp’: drivers/video/console/fbcon.c:1369:3: warning: statement with no effect drivers/video/console/fbcon.c:1371:3: warning: statement with no effect This is because several functions in include/linux/vt_kern.h are defined to (0).

This device is used by some of the Intel MID platforms. It's not similar enough to the MAX3100 to use the same driver. At this point the driver is specific to the platform and not generalised.

2010-08-10tty: avoid recursive BTM in pty_closeArnd Bergmann
When the console has been redirected, a hangup of the tty will cause tty_release to be called under the big tty_mutex, which leads to a deadlock because hangup is also called under the BTM. This moves the BTM deeper into the tty_hangup function so we can close the redirected tty without holding the BTM. In case of pty, we now need to drop the BTM before calling tty_vhangup.

2010-08-10tty: release BTM while sleeping in block_til_readyArnd Bergmann
Most tty drivers may block while opening a device. Since this possibly depends on another thread closing it first and both threads may need the BTM, we need to release it here.

2010-08-10tty: implement BTM as mutex instead of BKLArnd Bergmann
The tty locking now follows the rules for mutexes, so we can replace the BKL usage with a new subsystem wide mutex. Using a regular mutex here will change the behaviour when blocked on the BTM from spinning to sleeping, but that should not be visible to the user. Using the mutex also means that all the BTM is now covered by lockdep.

2010-08-10tty: remove tty_lock_nestedArnd Bergmann
This changes all remaining users of tty_lock_nested to be non-recursive, which lets us kill this function. As a consequence, we won't need to keep the lock count any more, which allows more simplifications later.
