2013-12-31Input: cros_ec_keyb - fix problems with backslashDoug Anderson1-4/+11
The driver can't deal with two entries its keymap having the same keycode. When this happens it will get confused about whether the key is down or up and will cause some screwy behavior. We need to have two entries for KEY_BACKSLASH to handle US and UK keyboards. Specifically: * On the US keyboard the backslash key (above enter) is r3 c11 and is supposed to be reported as BACKSLASH. * On the UK keyboard the # key (left of enter) is r4 c10 and is supposed to be reported as BACKSLASH. * On the UK keyboard the \ key (left of Z) is r2 c7 and is supposed to be reported as KEY_102ND. Note that both keyboards (US and UK) have only one physical backslash key so the constraint that each physical key should have its own keycode still stands.

git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux into next/cleanup From Stephen Warren: ARM: tegra: implement common DMA and resets DT bindings This series converts the Tegra DTs and drivers to use the common/ standard DMA and reset bindings, rather than custom bindings. It also adds complete documentation for the Tegra clock bindings without actually changing any binding definitions. This conversion relies on a few sets of patches in branches from outside the Tegra tree: 1) A patch to add an DMA channel request API which allows deferred probe to be implemented. 2) A patch to implement a common part of the of_xlate function for DMA controllers. 3) Some ASoC patches (which in turn rely on (1) above), which support deferred probe during DMA channel allocation. 4) The Tegra clock driver changes for 3.14. Consequently, this branch is based on a merge of all of those external branches. In turn, this branch is or will be pulled into a few places that either rely on features introduced here, or would otherwise conflict with the patches: a) Tegra's own for-3.14/powergate and for-4.14/dt branches, to avoid conflicts. b) The DRM tree, which introduces new code that relies on the reset controller framework introduced in this branch, and to avoid conflicts. * tag 'tegra-for-3.14-dmas-resets-rework' of git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux: (30 commits) spi: tegra: checking for ERR_PTR instead of NULL ASoC: tegra: update module reset list for Tegra124 clk: tegra: remove bogus PCIE_XCLK clk: tegra: remove legacy reset APIs ARM: tegra: remove legacy DMA entries from DT ARM: tegra: remove legacy clock entries from DT USB: EHCI: tegra: use reset framework Input: tegra-kbc - use reset framework serial: tegra: convert to standard DMA DT bindings serial: tegra: use reset framework spi: tegra: convert to standard DMA DT bindings spi: tegra: use reset framework staging: nvec: use reset framework i2c: tegra: use reset framework ASoC: tegra: convert to standard DMA DT bindings ASoC: tegra: allocate AHUB FIFO during probe() not startup() ASoC: tegra: call pm_runtime APIs around register accesses ASoC: tegra: use reset framework dma: tegra: register as an OF DMA controller dma: tegra: use reset framework ...

2013-12-18Input: elantech - improve clickpad detectionHans de Goede1-3/+42
The current assumption in the elantech driver that hw version 3 touchpads are never clickpads and hw version 4 touchpads are always clickpads is wrong. There are several bug reports for this, ie: https://bugzilla.redhat.com/show_bug.cgi?id=1030802 http://superuser.com/questions/619582/right-elantech-touchpad-button-not-working-in-linux I've spend a couple of hours wading through various bugzillas, launchpads and forum posts to create a list of fw-versions and capabilities for different laptop models to find a good method to differentiate between clickpads and versions with separate hardware buttons. Which shows that a device being a clickpad is reliable indicated by bit 12 being set in the fw_version. I've included the gathered list inside the driver, so that we've this info at hand if we need to revisit this later.

2013-12-15Input: zforce - fix possible driver hang during suspendHeiko Stübner1-6/+15
handle_level_irq masks the interrupt before handling it, and only unmasks it after the handler is finished. So when a touch event happens after threads are suspended, but before the system is fully asleep the irq handler tries to wakeup the thread which will only happen on the next resume, resulting in the wakeup event never being sent and the driver not being able to wake the system from sleep due to the masked irq. Therefore move the wakeup_event to a small non-threaded handler. Signed-off-by: Heiko Stuebner <[email protected]> Signed-off-by: Dmitry Torokhov <[email protected]>

2013-12-07ACPI: Clean up inclusions of ACPI header filesLv Zheng1-1/+1
Replace direct inclusions of <acpi/acpi.h>, <acpi/acpi_bus.h> and <acpi/acpi_drivers.h>, which are incorrect, with <linux/acpi.h> inclusions and remove some inclusions of those files that aren't necessary. First of all, <acpi/acpi.h>, <acpi/acpi_bus.h> and <acpi/acpi_drivers.h> should not be included directly from any files that are built for CONFIG_ACPI unset, because that generally leads to build warnings about undefined symbols in !CONFIG_ACPI builds. For CONFIG_ACPI set, <linux/acpi.h> includes those files and for CONFIG_ACPI unset it provides stub ACPI symbols to be used in that case. Second, there are ordering dependencies between those files that always have to be met. Namely, it is required that <acpi/acpi_bus.h> be included prior to <acpi/acpi_drivers.h> so that the acpi_pci_root declarations the latter depends on are always there. And <acpi/acpi.h> which provides basic ACPICA type declarations should always be included prior to any other ACPI headers in CONFIG_ACPI builds. That also is taken care of including <linux/acpi.h> as appropriate.

2013-12-01Input: usbtouchscreen - separate report and transmit buffer size handlingChristian Engelmayer1-4/+18
This patch supports the separate handling of the USB transfer buffer length and the length of the buffer used for multi packet support. For devices supporting multiple report or diagnostic packets, the USB transfer size is now limited to the USB endpoints wMaxPacketSize - otherwise it defaults to the configured report packet size as before. This fixes an issue where event reporting can be delayed for an arbitrary time for multi packet devices. For instance the report size for eGalax devices is defined to the 16 byte maximum diagnostic packet size as opposed to the 5 byte report packet size. In case the driver requests 16 byte from the USB interrupt endpoint, the USB host controller driver needs to split up the request into 2 accesses according to the endpoints wMaxPacketSize of 8 byte. When the first transfer is answered by the eGalax device with not less than the full 8 byte requested, the host controller has got no way of knowing whether the touch controller has got additional data queued and will issue the second transfer. If per example a liftoff event finishes at such a wMaxPacketSize boundary, the data will not be available to the usbtouch driver until a further event is triggered and transfered to the host. From user perspective the BTN_TOUCH release event in this case is stuck until the next touch down event.
