Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input
Pull input updates from Dmitry Torokhov: - several device tree bindings for input devices have been converted to yaml - dropped no longer used ixp4xx-beeper and CSR Prima2 PWRC drivers - analog joystick has been converted to use ktime API and no longer warn about low resolution timers - a few driver fixes * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input: (24 commits) Input: analog - always use ktime functions Input: mms114 - support MMS134S Input: elan_i2c - reduce the resume time for controller in Whitebox Input: edt-ft5x06 - added case for EDT EP0110M09 Input: adc-keys - drop bogus __refdata annotation Input: Fix spelling mistake in Kconfig "useable" -> "usable" Input: Fix spelling mistake in Kconfig "Modul" -> "Module" Input: remove dead CSR Prima2 PWRC driver Input: adp5589-keys - use the right header Input: adp5588-keys - use the right header dt-bindings: input: tsc2005: Convert to YAML schema Input: ep93xx_keypad - prepare clock before using it dt-bindings: input: sun4i-lradc: Add wakeup-source dt-bindings: input: Convert Regulator Haptic binding to a schema dt-bindings: input: Convert Pixcir Touchscreen binding to a schema dt-bindings: input: Convert ChipOne ICN8318 binding to a schema Input: pm8941-pwrkey - fix comma vs semicolon issue dt-bindings: power: reset: qcom-pon: Convert qcom PON binding to yaml dt-bindings: input: pm8941-pwrkey: Convert pm8941 power key binding to yaml dt-bindings: power: reset: Change 'additionalProperties' to true ...
