Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input
Pull input subsystem updates from Dmitry Torokhov: "- we finally merged driver for USB version of Synaptics touchpads (I guess most commonly found in IBM/Lenovo keyboard/touchpad combo); - a bunch of new drivers for embedded platforms (Cypress touchscreens, DA9052 OnKey, MAX8997-haptic, Ilitek ILI210x touchscreens, TI touchscreen); - input core allows clients to specify desired clock source for timestamps on input events (EVIOCSCLOCKID ioctl); - input core allows querying state of all MT slots for given event code via EVIOCGMTSLOTS ioctl; - various driver fixes and improvements." * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input: (45 commits) Input: ili210x - add support for Ilitek ILI210x based touchscreens Input: altera_ps2 - use of_match_ptr() Input: synaptics_usb - switch to module_usb_driver() Input: convert I2C drivers to use module_i2c_driver() Input: convert SPI drivers to use module_spi_driver() Input: omap4-keypad - move platform_data to <linux/platform_data> Input: kxtj9 - who_am_i check value and initial data rate fixes Input: add driver support for MAX8997-haptic Input: tegra-kbc - revise device tree support Input: of_keymap - add device tree bindings for simple key matrices Input: wacom - fix physical size calculation for 3rd-gen Bamboo Input: twl4030-vibra - really switch from #if to #ifdef Input: hp680_ts_input - ensure arguments to request_irq and free_irq are compatible Input: max8925_onkey - avoid accessing input device too early Input: max8925_onkey - allow to be used as a wakeup source Input: atmel-wm97xx - convert to dev_pm_ops Input: atmel-wm97xx - set driver owner Input: add cyttsp touchscreen maintainer entry Input: cyttsp - remove useless checks in cyttsp_probe() Input: usbtouchscreen - add support for Data Modul EasyTouch TP 72037 ...
