* Revert "USB host: Move AMD PLL quirk to pci-quirks.c"Greg Kroah-Hartman2011-02-17
| | | | | | | | | | | | | This reverts commit b7d5b439b7a40dd0a0202fe1c118615a3fcc3b25. It conflicts with commit baab93afc2844b68d57b0dcca5e1d34c5d7cf411 "USB: EHCI: ASPM quirk of ISOC on AMD Hudson" and merging the two just doesn't work properly.

* USB: gadget: f_fs: even zero-length packets require a bufferMarek Szyprowski2011-02-04
| | | | | | | | | | | | Some UDC drivers fails to queue a request if req->buf == NULL even for ZLP requests. This patch adds a poisoned pointer instead of NULL to make the code compliant with the gadget specification and catches possible bug in the UDC driver if it tries to dereference buffer pointer on ZLP request.

* USB: HCD: Add driver hooks for (un)?map_urb_for_dmaRobert Morell2011-02-04
| | | | | | | | | | | | | | | | | Provide optional hooks for the host controller driver to override the default DMA mapping and unmapping routines. In general, these shouldn't be necessary unless the host controller has special DMA requirements, such as alignment contraints. If these are not specified, the general usb_hcd_(un)?map_urb_for_dma functions will be used instead. Also, pass the status to unmap_urb_for_dma so it can know whether the DMA buffer has been overwritten. Finally, add a flag to be used by these implementations if they allocated a temporary buffer so it can be freed properly when unmapping.

* USB: usbmon: fix-up docs and text API for sparse ISOPete Zaitcev2011-02-04
| | | | | | | | | | | | | | This is based on a patch that Alan Stern wrote. It did the same simple thing in both text and binary cases. In the same time, Marton and I fixed the binary side properly, but this leaves the text to be fixed. It is not very important due to low maxium data size of text, but let's add it just for extra correctness. The pseudocode is too much to keep fixed up, and we have real code to be used as examples now, so let's drop it too.

* USB: EHCI: Rearrange create_companion_file() to avoid GCC-4.6 warnings.David Daney2011-02-04
| | | | | | | | | | | | | | | | | | | In create_companion_file() there is a bogus assignemt to i created for the express purpose of avoiding an ignored return value warning. With pre-release GCC-4.6, this causes a 'set but not used' warning. Kick the problem further down the road by just returning i. All the callers of create_companion_file() ignore its return value, so all is good: o No warnings are issued. o We still subvert the desires of the authors of device_create_file() by ignorning error conditions.

With pre-release GCC-4.6, there are several complaints of variables that are 'set but not used' caused by the ehci_vdbg() macro expanding to something that does not contain any of its arguments.

* USB host: Move AMD PLL quirk to pci-quirks.cAndiry Xu2011-02-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch moves the AMD PLL quirk code in OHCI/EHCI driver to pci-quirks.c, and exports the functions to be used by xHCI driver later. AMD PLL quirk disable the optional PM feature inside specific SB700/SB800/Hudson-2/3 platforms under the following conditions: 1. If an isochronous device is connected to OHCI/EHCI/xHCI port and is active; 2. Optional PM feature that powers down the internal Bus PLL when the link is in low power state is enabled. Without AMD PLL quirk, USB isochronous stream may stutter or have breaks occasionally, which greatly impair the performance of audio/video streams. Currently AMD PLL quirk is implemented in OHCI and EHCI driver, and will be added to xHCI driver too. They are doing similar things actually, so move the quirk code to pci-quirks.c, which has several advantages: 1. Remove duplicate defines and functions in OHCI/EHCI (and xHCI) driver and make them cleaner; 2. AMD chipset information will be probed only once and then stored. Currently they're probed during every OHCI/EHCI initialization, move the detect code to pci-quirks.c saves the repeat detect cost; 3. Build up synchronization among OHCI/EHCI/xHCI driver. In current code, every host controller enable/disable PLL only according to its own status, and may enable PLL while there is still isoc transfer on other HCs. Move the quirk to pci-quirks.c prevents this issue.

| | | | | | | | | | | | | Currently, for ISO and INT, a protocol driver must chose the value for wMaxPacketSize arbitrarily. The value may be too low, resulting in lesser than efficient operation or high enough to not work with all UDC drivers.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A number of things going on here, but the end result is that the IR part on the hdpvr gets enabled, and can be used with ir-kbd-i2c and/or lirc_zilog. First up, there are some conditional build fixes that come into play whether i2c is built-in or modular. Second, we're swapping out i2c_new_probed_device() for i2c_new_device(), as in my testing, probing always fails, but we *know* that all hdpvr devices have a z8 chip at 0x70 and 0x71. Third, we're poking at an i2c address directly without a client, and writing some magic bits to actually turn on this IR part (this could use some improvement in the future). Fourth, some of the i2c_adapter storage has been reworked, as the existing implementation used to lead to an oops following i2c changes c. 2.6.31. Earlier editions of this patch have been floating around the 'net for a while, including being patched into Fedora kernels, and they *do* work. This specific version isn't yet tested, beyond loading ir-kbd-i2c and confirming that it does bind to the RX address of the hdpvr. [mchehab@redhat.com: I2C_CLASS_TV_ANALOG is not defined.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix a bug in v4l2_device_unregister where the sd pointer can be dereferenced after it was freed. Normally the i2c adapter is removed before this function is called. Removing the adapter will also unregister all subdevs on that adapter, so generally v4l2_device_unregister has nothing to do. However, in the case of a platform i2c bus that bus is generally not freed. In that case, after freeing the i2c subdevice the code will fall into the second block when it tests if the subdev is a SPI device. But by that time the subdev is already freed and the kernel oopses. The fix is trivial: continue with the loop after freeing the i2c or spi subdevice.

This allows us to assume that ir->tx != NULL in a few places in the driver, and also allows us to always report Tx is available to userspace. Get rid of unneeded tests for ir->tx == NULL and always report that Tx is available. Signed-off-by: Andy Walls <awalls@md.metrocast.net> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
| * [media] lirc_zilog: Update IR Rx polling kthread start/stop and some printksAndy Walls2011-01-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The IR Rx polling thread was originally a kernel_thread long ago, and had only been minimally converted to a kthread. This patch finishes that conversion by - cleaning up all the unneeded completions - destroying the kthread properly by calling kthread_stop() - changing lirc_thread() to test kthread_should_stop() just before every point where it may sleep - reorganizing the lirc_thread() function so it uses fewer lines - modifying the name of the kthread from "lirc_zilog" to "zilog-rx-i2c-N", so ps will show which kthread polls which Zilog Z8 IR unit. Also some minor tweaks were made to logging emitted by the ir_probe() function. Signed-off-by: Andy Walls <awalls@md.metrocast.net> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
| * [media] lirc_zilog: Extensive rework of ir_probe()/ir_remove()Andy Walls2011-01-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is an extensive rework of the ir_probe() and ir_remove() functions. It removes all the double binding and allocation problems on module load. It removes almost all the memory leaks on module exit and on device instantiation failure. Proper destruction of the Rx polling kthread still needs investigation and more work, but it is no worse than it already was. This rework also had side effects that include: - encapsulation of the ir_devices[] array - serialization of access to the ir_devices[] array - semantic change of the module parameter "disable_rx" to "tx_only" If tx_only is true, the module does not claim the i2c_client for the IR Rx function, and only claims and handles the i2c_client for the IR Tx function. This is a first step in providing the option of letting ir-kbd-i2c.c handle IR Rx function, while lirc_zilog handles the IR Tx function.

| * [media] lirc_zilog: Don't make private copies of i2c clientsAndy Walls2011-01-19
| | | | | | | | | | | | | | | | | | | | Don't make private copies of the i2c clients provided by the I2C subsystem, don't change the client address field, and don't probe the client addresses - the bridge driver already did that. This moves us to the proper I2C and binding model. Signed-off-by: Andy Walls <awalls@md.metrocast.net> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
