Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input
Pull input layer updates from Dmitry Torokhov: - a bunch of new drivers (DA9052/53 touchscreenn controller, Synaptics Navpoint, LM8333 keypads, Wacom I2C touhscreen); - updates to existing touchpad drivers (ALPS, Sntelic); - Wacom driver now supports Intuos5; - device-tree bindings in numerous drivers; - other cleanups and fixes. Fix annoying conflict in drivers/input/tablet/wacom_wac.c that I think implies that the input layer device naming is broken, but let's see. I brough it up with Dmitry. * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input: (57 commits) Input: matrix-keymap - fix building keymaps Input: spear-keyboard - document DT bindings Input: spear-keyboard - add device tree bindings Input: matrix-keymap - wire up device tree support Input: matrix-keymap - uninline and prepare for device tree support Input: adp5588 - add support for gpio names Input: omap-keypad - dynamically handle register offsets Input: synaptics - fix compile warning MAINTAINERS: adjust input-related patterns Input: ALPS - switch to using input_mt_report_finger_count Input: ALPS - add semi-MT support for v4 protocol Input: Add Synaptics NavPoint (PXA27x SSP/SPI) driver Input: atmel_mxt_ts - dump each message on just 1 line Input: atmel_mxt_ts - do not read extra (checksum) byte Input: atmel_mxt_ts - verify object size in mxt_write_object Input: atmel_mxt_ts - only allow root to update firmware Input: atmel_mxt_ts - use CONFIG_PM_SLEEP Input: sentelic - report device's production serial number Input: tl6040-vibra - Device Tree support Input: evdev - properly handle read/write with count 0 ...
