Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input
Pull input updates from Dmitry Torokhov: "Items of note: - evdev users can now limit or mask the kind of events they will receive. This will allow applications such as power manager or network manager to only be woken when user presses special keys such as KEY_POWER or KEY_WIFI and not be bothered with ordinary key presses coming from keyboard - support for FocalTech FT6236 touchscreen controller - support for ROHM BU21023/24 touchscreen controller - edt-ft5x06 touchscreen driver got a face lift and can now be used with FT5506 - support for Google Fiber TV Box remote controls - improvements in xpad driver (with more to come) - several parport-based drivers have been switched to the new device model - other miscellaneous driver improvements" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input: (70 commits) HID: hid-gfrm: avoid warning for input_configured API change HID: hid-input: allow input_configured callback return errors Input: evdev - fix bug in checking duplicate clock change request Input: add userio module Input: evdev - add event-mask API Input: snvs_pwrkey - remove duplicated semicolon HID: hid-gfrm: Google Fiber TV Box remote controls Input: e3x0-button - update Kconfig description Input: tegra-kbc - drop use of IRQF_NO_SUSPEND flag Input: tegra-kbc - enable support for the standard "wakeup-source" property Input: xen - check return value of xenbus_printf Input: hp_sdc_rtc - fix y2038 problem in proc_show Input: nomadik-ske-keypad - fix a trivial typo Input: xpad - fix clash of presence handling with LED setting Input: edt-ft5x06 - work around FT5506 firmware bug Input: edt-ft5x06 - add support for FT5506 Input: edt-ft5x06 - add support for different max support points Input: edt-ft5x06 - use max support points to determine how much to read Input: rotary-encoder - add support for quarter-period mode Input: rotary-encoder - use of_property_read_bool ...

+* Dialog DA9062/63 OnKey Module
+
+This module is part of the DA9062/DA9063. For more details about entire
+chips see Documentation/devicetree/bindings/mfd/da9062.txt and
+Documentation/devicetree/bindings/mfd/da9063.txt
+
+This module provides KEY_POWER, KEY_SLEEP and events.
+
+Required properties:
+
+- compatible: should be one of:
+ dlg,da9062-onkey
+ dlg,da9063-onkey
+
+Optional properties:
+
+ - dlg,disable-key-power : Disable power-down using a long key-press. If this
+ entry exists the OnKey driver will remove support for the KEY_POWER key
+ press. If this entry does not exist then by default the key-press
+ triggered power down is enabled and the OnKey will support both KEY_POWER
+ and KEY_SLEEP.
+
+Example:
+
+ pmic0: da9062@58 {
+
+ onkey {
+ compatible = "dlg,da9063-onkey";
+ dlg,disable-key-power;
+ };
+
+ };

+- rotary-encoder,steps-per-period: Number of steps (stable states) per period.
