Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input
Pull input subsystem updates from Dmitry Torokhov: - updated support for Synaptics RMI4 devices, including support for SMBus controllers, firmware update support, sensor tuning, and PS/2 guest support - ALPS driver now supports tracksticks on SS5 controllers - i8042 now uses chassis info to skip selftest on Asus laptops as list of individual models became too unwieldy - miscellaneous fixes to other drivers * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input: (67 commits) Input: imx6ul_tsc - generalize the averaging property Input: drv260x - use generic device properties Input: drv260x - use temporary for &client->dev Input: drv260x - fix input device's parent assignment Input: synaptics-rmi4 - add support for F34 V7 bootloader Input: drv260x - fix initializing overdrive voltage Input: ALPS - fix protcol -> protocol Input: i8042 - comment #else/#endif of CONFIG_PNP Input: lpc32xx-keys - fix invalid error handling of a requested irq Input: synaptics-rmi4 - fix debug for sensor clip Input: synaptics-rmi4 - store the attn data in the driver Input: synaptics-rmi4 - allow to add attention data Input: synaptics-rmi4 - f03 - grab data passed by transport device Input: synaptics-rmi4 - add support for F03 Input: imx6ul_tsc - convert int to u32 Input: imx6ul_tsc - add mask when set REG_ADC_CFG Input: synaptics-rmi4 - have only one struct platform data Input: synaptics-rmi4 - remove EXPORT_SYMBOL_GPL for internal functions Input: synaptics-rmi4 - remove mutex calls while updating the firmware Input: drv2667 - fix misuse of regmap_update_bits ...
