* | | | Input: tsc2005 - add DT supportSebastian Reichel2014-05-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds DT support to the tsc2005 touchscreen driver. It also adds regulator support to the driver if booted via DT.

* | | | Input: add common DT binding for touchscreensSebastian Reichel2014-05-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add common DT binding documentation for touchscreen devices and implement input_parse_touchscreen_of_params, which parses the common properties and configures the input device accordingly. The method currently does not interpret the axis inversion properties, since there is no matching flag in the generic linux input device.

This change replaces the msleep with a wait for completion that the mxt_interrupt handler signals. Also add CHG poll after last firmware frame - some bootloader versions will assert the interrupt line after the final frame, in testing this meant that the driver attempts to read the info block too early whilst the chip is still resetting. This improves firmware update time as we no longer wait longer than necessary for each reset.

It makes life difficult when tuning the device to keep them in sync with the config array/file, and requires a new kernel build for minor tweaks. These parameters only represent a tiny subset of the available configuration options, tracking all of these options in platform data would be a endless task. In addition, different versions of maXTouch chips may have these values in different places or may not even have them at all. Having these values also makes life more complex for device tree and other platforms where having to define a static configuration isn't helpful.

You will also get more quirks for Synaptics touchpads in various Lenovo laptops, a change to elantech driver to recognize even more models, and fixups to wacom and couple other drivers" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input: Input: elantech - add support for newer elantech touchpads Input: soc_button_array - fix a crash during rmmod Input: synaptics - add min/max quirk for ThinkPad T431s, L440, L540, S1 Yoga and X1 Input: synaptics - report INPUT_PROP_TOPBUTTONPAD property Input: Add INPUT_PROP_TOPBUTTONPAD device property Input: i8042 - add firmware_id support Input: serio - add firmware_id sysfs attribute Input: wacom - handle 1024 pressure levels in wacom_tpc_pen Input: wacom - references to 'wacom->data' should use 'unsigned char*' Input: wacom - override 'pressure_max' with value from HID_USAGE_PRESSURE Input: wacom - use full 32-bit HID Usage value in switch statement Input: wacom - missed the last bit of expresskey for DTU-1031 Input: ads7846 - fix device usage within attribute show Input: da9055_onkey - remove use of regmap_irq_get_virq()
| | * Input: elantech - add support for newer elantech touchpadsJordan Rife2014-04-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Newer elantech touchpads are not recognized by the current driver, since it fails to detect their firmware version number. This prevents more advanced touchpad features from being usable such as two-finger scrolling. This patch allows newer touchpads to be detected and be fully functional. Tested on Sony Vaio SVF13N17PXB. Signed-off-by: Jordan Rife <jrife0@gmail.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | When the system has zero or one button available, trying to rmmod soc_button_array will cause crash. Fix this by properly handling -ENODEV in probe(). Signed-off-by: Lejun Zhu <lejun.zhu@linux.intel.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
| | * Input: synaptics - add min/max quirk for ThinkPad T431s, L440, L540, S1 Yoga ↵Hans de Goede2014-04-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | and X1 We expect that all the Haswell series will need such quirks, sigh. The T431s seems to be T430 hardware in a T440s case, using the T440s touchpad, with the same min/max issue. The X1 Carbon 3rd generation name says 2nd while it is a 3rd generation. The X1 and T431s share a PnPID with the T540p, but the reported ranges are closer to those of the T440s. HdG: Squashed 5 quirk patches into one. T431s + L440 + L540 are written by me, S1 Yoga and X1 are written by Benjamin Tissoires. Hdg: Standardized S1 Yoga and X1 values, Yoga uses the same touchpad as the X240, X1 uses the same touchpad as the T440.

| | * Input: serio - add firmware_id sysfs attributeHans de Goede2014-04-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | serio devices exposed via platform firmware interfaces such as ACPI may provide additional identifying information of use to userspace. We don't associate the serio devices with the firmware device (we don't set it as parent), so there's no way for userspace to make use of this information. We cannot change the parent for serio devices instantiated though a firmware interface as that would break suspend / resume ordering. Therefore this patch adds a new firmware_id sysfs attribute so that userspace can get a string from there with any additional identifying information the firmware interface may provide.
