2014-01-07Input: delete non-required instances of include <linux/init.h>Paul Gortmaker1-1/+0
None of these files are actually using any __init type directives and hence don't need to include <linux/init.h>. Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next.

2012-09-19Input: MT - Add flags to input_mt_init_slots()Henrik Rydberg1-1/+1
Preparing to move more repeated code into the mt core, add a flags argument to the input_mt_slots_init() function.

2012-04-04Input: serio - use module_serio_driverAxel Lin1-12/+1
This patch converts the drivers in drivers/input/* to use module_serio_driver() macro which makes the code smaller and a bit simpler. Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

2011-09-08Input: wacom - add POINTER and DIRECT device propertiesJason Gerecke1-0/+2
Adds INPUT_PROP_POINTER or INPUT_PROP_DIRECT as necessary to the hardware supported by the Wacom driver. The DIRECT property is assigned to devices with an embedded screen (i.e. touchscreens and display tablets). The POINTER property is assigned to those without embedded screens.

2011-08-24Input: wacom_w8001 - simplify w8001_removeDmitry Torokhov1-4/+4
Since touchscreen driver does not handle any events to be sent to the device we can close serio port first and then unregister the input device. Tested-by: Ping Cheng <pingc@wacom.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2011-08-24Input: wacom_w8001 - implement open and closeDmitry Torokhov1-1/+20
Implement open() and close() methods for the input device so that we do not start the device unless there are users listening to the events. Acked-by: Chris Bagwell <chris@cnpbagwell.com> Tested-by: Ping Cheng <pingc@wacom.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2011-02-01Input: wacom_w8001 - report resolution to userlandPing Cheng1-2/+11
Serial devices send both pen and touch data through the same logical port. Since we scaled touch to pen maximum, we use pen resolution for touch as well here. This is under the assumption that pen and touch share the same physical surface. In the case when a small physical dimensional difference occurs between pen and touch, we assume the tolerance for touch point precision is higher than pen and the difference is within touch point tolerance. A per-MT tool based resolution mechanism should be introduced if the above assumption does not hold true for the pen and touch devices any more.

2011-01-11Input: wacom_w8001 - add single-touch supportPing Cheng1-33/+149
Emulate single-touch compatible events for the 2-finger panels so that they can be used with single-touch legacy clients. Assign device ids as Wacom USB vendor ID and product ID. Name the device to reflect its specific features. Scale touch coordinates to pen maximum if pen supported. Signed-off-by: Ping Cheng <pingc@wacom.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2010-12-30Input: wacom_w8001 - support pen or touch only devicesPing Cheng1-12/+32
Not all penabled devices support touch. The same holds true for touch devices, so we should be setting up devices according to the results returned when we query the hardware. Signed-off-by: Ping Cheng <pingc@wacom.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

2010-12-16input: mt: Move tracking and pointer emulation to input-mtHenrik Rydberg1-16/+5
The drivers using the type B protocol all report tracking information the same way. The contact id is semantically equivalent to ABS_MT_SLOT, and the handling of ABS_MT_TRACKING_ID only complicates the driver. The situation can be improved upon by providing a common pointer emulation code, thereby removing the need for the tracking id in the driver. This patch moves all tracking event handling over to the input core, simplifying both the existing drivers and the ones currently in preparation.

2010-12-16input: mt: Collect slots initialization codeHenrik Rydberg1-1/+1
The MT slots devices all follow the same initialization pattern of creating slots and hinting about buffer size. Let drivers call an initialization function instead, and make sure it can be called repeatedly without side effects. Signed-off-by: Henrik Rydberg <rydberg@euromail.se>

2010-08-29Input: wacom_w8001 - add multitouch slot supportPeter Hutterer1-3/+46
Some serial wacom devices support two-finger touch. Test for this during init and parse the touch packets accordingly. Touch packets are processed using Protocol B (MT Slots). Note: there are several wacom versions that do touch but not two-finger touch. These are not catered for here, touch events for these are simply discarded.

Tablets that support touch input may report different sized packages, depending on the touch sensor in the tablet. For now, discard the packages until we report them as touch input proper. Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2010-08-29Input: wacom_w8001 - send BTN_TOOL_PEN/RUBBER and BTN_STYLUS eventsPeter Hutterer1-6/+48
The protocol used by the w8001 supports status fields for tip, side switch and eraser as well as a RDY field for proximity. The protocol has a double usage for the f2 bit in the packet. If set, the data is either pen + side2 button or eraser. Assume eraser if the device comes into proximity with the f2 bit set, otherwise trigger the side2 button. If the device comes into proximity with the f2 bit and that bit disappears afterwards, fake proximity out for the eraser and proximity in for the pen.
