* Input: atmel_mxt_ts - set pointer emulation on touchpadsBenson Leung2014-07-23
| | | | | | | | | | | Touchpads are pointers, so make sure to pass the correct values to input_mt_report_pointer_emulation(). Without this, tap-to-click doesn't work.

* Input: atmel_mxt_ts - move input device init into separate functionNick Dyer2014-07-23
| | | | | | | | | | | | | | | | | It is useful to initialise the input device later: - Screen parameters may not be not known yet, for instance if waiting for firmware loader to return. - Device may be in bootloader mode on probe (but could still be recovered by firmware download). In addition, later devices have a different touchscreen object (T100) which requires handling differently. This also reduces the complexity of the probe function.

* Input: atmel_mxt_ts - initialise IRQ before probingNick Dyer2014-07-23
| | | | | | | | | | | | | | | | | The maXTouch chips use the CHG line to generate status events in bootloader mode, and during configuration download, before there is enough information to configure the input device. Therefore set up the interrupt handler earlier. However, this introduces states where parts of the interrupt processing must not run. Use data->object_table as a way to tell whether the chip information is valid, and data->input_dev as a way to tell whether it is valid to generate input report.

* Input: add support for Wacom protocol 4 serial tabletsHans de Goede2014-07-20
| | | | | | | | | | | | | | | | | Recent version of xf86-input-wacom no longer support directly accessing serial tablets. Instead xf86-input-wacom now expects all wacom tablets to be driven by the kernel and to show up as evdev devices. This has caused old serial Wacom tablets to stop working for people who still have such tablets. Julian Squires has written a serio input driver to fix this: https://github.com/tokenrove/wacom-serial-iv This is a cleaned up version of this driver with improved Graphire support (I own an old Graphire myself).

| | | | | | | | | | | | This patch introduces the use of managed interfaces like devm_kzalloc, devm_input_allocate_device, devm_request_threaded_irq etc. and does away with the calls to free the allocated memory.

* Input: add driver for Microchip's CAP1106Daniel Mack2014-07-18
| | | | | | | | | | | | | | | | | | | | | This patch adds a driver for Microchips CAP1106, an I2C driven, 6-channel capacitive touch sensor. For now, only the capacitive buttons are supported, and no specific settings that can be tweaked for individual channels, except for the device-wide sensitivity gain. The defaults seem to work just fine out of the box, so I'll leave configurable parameters for someone who's in need of them and who can actually measure the impact. All registers are prepared, however. Many of them are just not used for now. The implementation does not make any attempt to be compatible to platform data driven boards, but fully depends on CONFIG_OF. Power management functions are also left for volounteers with the ability to actually test them.

* Input: elantech - don't set bit 1 of reg_10 when the no_hw_res quirk is setHans de Goede2014-06-08
| | | | | | | | | | | | | | | | | | | | The touchpad on the GIGABYTE U2442 not only stops communicating when we try to set bit 3 (enable real hardware resolution) of reg_10, but on some BIOS versions also when we set bit 1 (enable two finger mode auto correct). I've asked the original reporter of: https://bugzilla.kernel.org/show_bug.cgi?id=61151 To check that not setting bit 1 does not lead to any adverse effects on his model / BIOS revision, and it does not, so this commit fixes the touchpad not working on these versions by simply never setting bit 1 for laptop models with the no_hw_res quirk.

* Input: elantech - deal with clickpads reporting right button eventsHans de Goede2014-06-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | At least the Dell Vostro 5470 elantech *clickpad* reports right button clicks when clicked in the right bottom area: https://bugzilla.redhat.com/show_bug.cgi?id=1103528 This is different from how (elantech) clickpads normally operate, normally no matter where the user clicks on the pad the pad always reports a left button event, since there is only 1 hardware button beneath the path. It looks like Dell has put 2 buttons under the pad, one under each bottom corner, causing this. Since this however still clearly is a real clickpad hardware-wise, we still want to report it as such to userspace, so that things like finger movement in the bottom area can be properly ignored as it should be on clickpads. So deal with this weirdness by simply mapping a right click to a left click on elantech clickpads. As an added advantage this is something which we can simply do on all elantech clickpads, so no need to add special quirks for this weird model.
