* Input: auo-pixcir-ts - handle reset gpio directlyHeiko Stübner2013-02-242-9/+21
| | | | | | | | | | | | | | | Devicetree based platforms don't handle device callbacks very well and until now no board has come along that needs more extended hwinit than pulling the rst gpio high. Therefore pull the reset handling directly into the driver and remove the callbacks from the driver. If extended device setup is needed at some later point, power-sequences would probably be the solution of choice.

* Input: tegra-kbc - require CONFIG_OF, remove platform dataStephen Warren2013-02-153-166/+93
| | | | | | | | | | | Tegra only supports, and always enables, device tree. Remove all ifdefs and runtime checks for DT support from the driver. Platform data is therefore no longer required. Delete the header that defines it, and rework the driver to parse the device tree directly into struct tegra_kbc.

| | | | | | | | | | | | | To properly setup event parameters for emulated events, pass the appropriate flag to the slot initialization function. Also, all MT-related events should be setup before initialization. Incidentally, this solves the issue of doubly filtered pointer events.

Fix also some comments regarding the unit of measurement to use for the range and bandwidth fields, the values are not actually expected to be in G or HZ, the code in bma150.c just uses the BMA150_RANGE_xxx and BMA150_BW_xxx constants like they are with no translation from actual values in G or HZ.

* Input: bma150 - fix checking pm_runtime_get_sync() return valueMichael Trimarchi2013-02-151-1/+1
| | | | | | | | | | | | | | | | | When PM_RUNTIME is not defined, pm_runtime_get_sync() returns 1, see include/linux/pm_runtime.c::__pm_runtime_resume(), and the check of the return value was overlooking this, in this case bma150_open() would return 1 which is not expected by upper layers. Maybe the check for != -ENOSYS (Function not implemented) was meant to cover this, but pm_runtime_get_sync() does not return this value. For now fix the issue locally by checking explicitly for negative return values.

* Input: synaptics - fix 1->3 contact transition reportingDaniel Kurtz2013-02-131-3/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Investigating the following gesture highlighted two slight implementation errors with choosing which slots to report in which slot when multiple contacts are present: Action SGM AGM (MTB slot:Contact) 1. Touch contact 0 (0:0) 2. Touch contact 1 (0:0, 1:1) 3. Lift contact 0 (1:1) 4. Touch contacts 2,3 (0:2, 1:3) In step 4, slot 1 was not being cleared first, which means the same tracking ID was being used for reporting both the old contact 1 and the new contact 3. This could result in "drumroll", where the old contact 1 would appear to suddenly jump to new finger 3 position. Similarly, if contacts 2 & 3 are not detected at the same sample, step 4 is split into two: Action SGM AGM (MTB slot:contact) 1. Touch contact 0 (0:0) 2. Touch contact 1 (0:0, 1:1) 3. Lift contact 0 (1:1) 4. Touch contact 2 (0:2, 1:1) 5. Touch contact 3 (0:2, 1:3) In this case, there was also a bug. In step 4, when contact 1 moves from SGM to AGM and contact 2 is first reported in SGM, slot 0 was actually empty. So slot 0 can be used to report the new SGM (contact 0), immediately. Since it was empty, contact 2 in slot 0 will get a new tracking ID. Signed-off-by: Daniel Kurtz <djkurtz@chromium.org> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

* Input: atkbd - fix multi-byte scancode handling on reconnectShawn Nematbakhsh2013-01-211-21/+51
| | | | | | | | | | | | | | | | | | | | | | On resume from suspend there is a possibility for multi-byte scancodes to be handled incorrectly. atkbd_reconnect disables the processing of scancodes in software by calling atkbd_disable, but the keyboard may still be active because no disconnect command was sent. Later, software handling is re-enabled. If a multi-byte scancode sent from the keyboard straddles the re-enable, only the latter byte(s) will be handled. In practice, this leads to cases where multi-byte break codes (ex. "e0 4d" - break code for right-arrow) are misread as make codes ("4d" - make code for numeric 6), leading to one or more unwanted, untyped characters being interpreted. The solution implemented here involves sending command f5 (reset disable) to the keyboard prior to disabling software handling of codes. Later, the command to re-enable the keyboard is sent only after we are prepared to handle scancodes.

Two finger touch devices are processed here since they will not use the updated input_mt_init_slots(), which does not offer benefit to those devices. input_mt_init_slots() will take care of ABS_X/Y assignment when flags are not zero.
