2016-11-18Input: synaptics-rmi4 - fix error handling in I2C transport driverGuenter Roeck
commit 261d7794c49b9a3bb5115c5ffc452e00f969bf43 upstream. Instantiating the rmi4 I2C transport driver without interrupts assigned (for example using manual i2c instantiation from the command line) caused the driver to fail to load, but it does not clean up its regulator or transport device registrations. Result is a crash at a later time, for example when rebooting the system.

2016-11-10Input: i8042 - add XMG C504 to keyboard reset tablePatrick Scheuring
commit da25311c7ca8b0254a686fc0d597075b9aa3b683 upstream. The Schenker XMG C504 is a rebranded Gigabyte P35 v2 laptop. Therefore it also needs a keyboard reset to detect the Elantech touchpad. Otherwise the touchpad appears to be dead. With this patch the touchpad is detected: $ dmesg | grep -E "(i8042|Elantech|elantech)" [ 2.675399] i8042: PNP: PS/2 Controller [PNP0303:PS2K,PNP0f13:PS2M] at 0x60,0x64 irq 1,12 [ 2.680372] i8042: Attempting to reset device connected to KBD port [ 2.789037] serio: i8042 KBD port at 0x60,0x64 irq 1 [ 2.791586] serio: i8042 AUX port at 0x60,0x64 irq 12 [ 2.813840] input: AT Translated Set 2 keyboard as /devices/platform/i8042/serio0/input/input4 [ 3.811431] psmouse serio1: elantech: assuming hardware version 4 (with firmware version 0x361f0e) [ 3.825424] psmouse serio1: elantech: Synaptics capabilities query result 0x00, 0x15, 0x0f.

commit f9a703a54d16ba2470391c4b12236ee56591d50c upstream. Just like Fujitsu CELSIUS H730, the H760 also has an Elantech touchpad with the same quirks. Without this patch, the touchpad is useless out-of-the-box as the mouse pointer won't move. This patch makes the driver aware of both the crc_enabled=1 requirement and the middle button, making the touchpad fully functional out-of-the-box.

2016-10-28Input: i8042 - skip selftest on ASUS laptopsMarcos Paulo de Souza
commit 930e19248e9b61da36c967687ca79c4d5f977919 upstream. On suspend/resume cycle, selftest is executed to reset i8042 controller. But when this is done in Asus devices, subsequent calls to detect/init functions to elantech driver fails. Skipping selftest fixes this problem. An easier step to reproduce this problem is adding i8042.reset=1 as a kernel parameter. On Asus laptops, it'll make the system to start with the touchpad already stuck, since psmouse_probe forcibly calls the selftest function. This patch was inspired by John Hiesey's change[1], but, since this problem affects a lot of models of Asus, let's avoid running selftests on them.

There are joystick devices that do not have those axes, for example TRC Rudder device. The device in question has ABS_Z, ABS_RX and ABS_RY axes causing it not being detected as joystick.

The silead touch-controller ICs use a different firmware per digitizer / tablet model. So there are going to be quite a few of then and they really should be under a separate subdir.

2016-09-10Input: silead_gsl1680 - document firmware-name, fix implementationHans de Goede
The driver has supported touchscreen-fw-name to specify the firmware to load since it has been merged, but this was omitted from the dt-binding documentation. During review of adding touchscreen-fw-name to the binding documentation it was brought up that there is a standard property name called "firmware-name" for this, which should be used. Since there are no users of touchscreen-fw-name yet, this commit adds documentation of "firmware-name" to the dt-binding documentation and switches the driver over to use this. This commit also makes the driver add a "silead/" prefix to the firmware name from dt before calling request_firmware. That the firmware files are stored under /lib/firmware/silead under Linux is an implementation detail and does not belong in devicetree.

2016-07-26Input: cros_ec_keyb - cleanup use of devDouglas Anderson
In cros_ec_keyb we stored "dev" in "struct cros_ec_keyb", but this was the EC's dev pointer and not the keyboard's. Let's clean this up to make it the keyboard's dev pointer. This could be useful in future patches but also has the nice effect of changing a few printouts to include the name of the keyboard device instead of the EC device, so we will see: [ 1.224648] cros-ec-keyb ff110000.spi:ec@0:keyboard-controller: valid_keys[00] = 0x14 instead of: [ 1.224505] cros-ec-spi spi0.0: valid_keys[00] = 0x14 Signed-off-by: Douglas Anderson <dianders@chromium.org> Signed-off-by: Brian Norris <briannorris@chromium.org> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input Pull input fixes from Dmitry Torokhov: "A few more fixes for the input subsystem: - restore naming for tsc2005 touchscreens as some userspace match on it - fix out of bound access in legacy keyboard driver - fixup in RMI4 driver Everything is tagged for stable as well" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input: Input: tsc200x - report proper input_dev name tty/vt/keyboard: fix OOB access in do_compute_shiftstate() Input: synaptics-rmi4 - fix maximum size check for F12 control register 8
2016-07-20Input: tsc200x - report proper input_dev nameMichael Welling
Passes input_id struct to the common probe function for the tsc200x drivers instead of just the bustype. This allows for the use of the product variable to set the input_dev->name variable according to the type of touchscreen used. Note that when we introduced support for TSC2004 we started calling everything TSC200X, so let's keep this quirk.

2016-07-19Input: synaptics-rmi4 - fix maximum size check for F12 control register 8Andrew Duggan
According to the RMI4 spec the maximum size of F12 control register 8 is 15 bytes. The current code incorrectly reports an error if control 8 is greater then 14. Making sensors with a control register 8 with 15 bytes unusable.

Extend touchscreen_parse_properties() with support for the touchscreen-inverted-x/y and touchscreen-swapped-x-y properties and add touchscreen_set_mt_pos() and touchscreen_report_pos() helper functions for storing coordinates into a input_mt_pos struct, or directly reporting them, taking these properties into account. This commit also modifies the existing callers of touchscreen_parse_properties() to pass in NULL for the new third argument, keeping the existing behavior.
