Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input
Pull input layer fixes from Dmitry Torokhov: "Fixes for v7 protocol for ALPS devices and few other driver fixes. Also users can request input events to be stamped with boot time timestamps, in addition to real and monotonic timestamps" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input: Input: hil_kbd - fix incorrect use of init_completion Input: alps - v7: document the v7 touchpad packet protocol Input: alps - v7: fix finger counting for > 2 fingers on clickpads Input: alps - v7: sometimes a single touch is reported in mt[1] Input: alps - v7: ignore new packets Input: evdev - add CLOCK_BOOTTIME support Input: psmouse - expose drift duration for IBM trackpoints Input: stmpe - bias keypad columns properly Input: stmpe - enforce device tree only mode mfd: stmpe: add pull up/down register offsets for STMPE Input: optimize events_per_packet count calculation Input: edt-ft5x06 - fixed a macro coding style issue Input: gpio_keys - replace timer and workqueue with delayed workqueue Input: gpio_keys - allow separating gpio and irq in device tree
