Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input
Pull input layer updates from Dmitry Torokhov: - evdev interface has been adjusted to extend the life of timestamps on 32 bit systems to the year of 2108 - Synaptics RMI4 driver's PS/2 guest handling ha beed updated to improve chances of detecting trackpoints on the pass-through port - mms114 touchcsreen controller driver has been updated to support generic device properties and work with mms152 cntrollers - Goodix driver now supports generic touchscreen properties - couple of drivers for AVR32 architecture are gone as the architecture support has been removed from the kernel - gpio-tilt driver has been removed as there are no mainline users and the driver itself is using legacy APIs and relies on platform data - MODULE_LINECSE/MODULE_VERSION cleanups * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input: (45 commits) Input: goodix - use generic touchscreen_properties Input: mms114 - fix typo in definition Input: mms114 - use BIT() macro instead of explicit shifting Input: mms114 - replace mdelay with msleep Input: mms114 - add support for mms152 Input: mms114 - drop platform data and use generic APIs Input: mms114 - mark as direct input device Input: mms114 - do not clobber interrupt trigger Input: edt-ft5x06 - fix error handling for factory mode on non-M06 Input: stmfts - set IRQ_NOAUTOEN to the irq flag Input: auo-pixcir-ts - delete an unnecessary return statement Input: auo-pixcir-ts - remove custom log for a failed memory allocation Input: da9052_tsi - remove unused mutex Input: docs - use PROPERTY_ENTRY_U32() directly Input: synaptics-rmi4 - log when we create a guest serio port Input: synaptics-rmi4 - unmask F03 interrupts when port is opened Input: synaptics-rmi4 - do not delete interrupt memory too early Input: ad7877 - use managed resource allocations Input: stmfts,s6sy671 - add SPDX identifier Input: remove atmel-wm97xx touchscreen driver ...
