Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input
Pull input updates from Dmitry Torokhov: "Two new touchpad drivers - Cypress APA I2C Trackpad and Cypress PS/2 touchpad and a big update to ALPS driver from Kevin Cernekee that adds support for "Rushmore" touchpads and paves way for adding support for "Dolphin" touchpads. There is also a new input driver for Goldfish emulator and also Android keyreset driver was folded into SysRq code. A few more drivers were updated with device tree bindings and others got some small cleanups and fixes." * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input: (55 commits) Input: cyttsp-spi - remove duplicate MODULE_ALIAS() Input: tsc2005 - add MODULE_ALIAS Input: tegra-kbc - require CONFIG_OF, remove platform data Input: synaptics - initialize pointer emulation usage Input: MT - do not apply filtering on emulated events Input: bma150 - make some defines public and fix some comments Input: bma150 - fix checking pm_runtime_get_sync() return value Input: ALPS - enable trackstick on Rushmore touchpads Input: ALPS - add support for "Rushmore" touchpads Input: ALPS - make the V3 packet field decoder "pluggable" Input: ALPS - move pixel and bitmap info into alps_data struct Input: ALPS - fix command mode check Input: ALPS - rework detection of Pinnacle AGx touchpads Input: ALPS - move {addr,nibble}_command settings into alps_set_defaults() Input: ALPS - use function pointers for different protocol handlers Input: ALPS - rework detection sequence Input: ALPS - introduce helper function for repeated commands Input: ALPS - move alps_get_model() down below hw_init code Input: ALPS - copy "model" info into alps_data struct Input: ALPS - document the alps.h data structures ...
