Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input
Pull input updates from Dmitry Torokhov: - three new touchscreen drivers: EETI EXC3000, HiDeep, and Samsung S6SY761 - the timer API conversion (setup_timer() -> timer_setup()) - a few drivers swiytched to using managed API for creating custom device attributes - other assorted fixed and cleanups. * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input: (50 commits) Input: gamecon - mark expected switch fall-throughs Input: sidewinder - mark expected switch fall-throughs Input: spaceball - mark expected switch fall-throughs Input: uinput - unlock on allocation failure in ioctl Input: add support for the Samsung S6SY761 touchscreen Input: add support for HiDeep touchscreen Input: st1232 - remove obsolete platform device support Input: convert autorepeat timer to use timer_setup() media: ttpci: remove autorepeat handling and use timer_setup Input: cyttsp4 - avoid overflows when calculating memory sizes Input: mxs-lradc - remove redundant assignment to pointer input Input: add I2C attached EETI EXC3000 multi touch driver Input: goodix - support gt1151 touchpanel Input: ps2-gpio - actually abort probe when connected to sleeping GPIOs Input: hil_mlc - convert to using timer_setup() Input: hp_sdc - convert to using timer_setup() Input: touchsceen - convert timers to use timer_setup() Input: keyboard - convert timers to use timer_setup() Input: uinput - fold header into the driver proper Input: uinput - remove uinput_allocate_device() ...

+Device-Tree bindings for GPIO attached mice
+
+This simply uses standard GPIO handles to define a simple mouse connected
+to 5-7 GPIO lines.
+
+Required properties:
+ - compatible: must be "gpio-mouse"
+ - scan-interval-ms: The scanning interval in milliseconds
+ - up-gpios: GPIO line phandle to the line indicating "up"
+ - down-gpios: GPIO line phandle to the line indicating "down"
+ - left-gpios: GPIO line phandle to the line indicating "left"
+ - right-gpios: GPIO line phandle to the line indicating "right"
+
+Optional properties:
+ - button-left-gpios: GPIO line handle to the left mouse button
+ - button-middle-gpios: GPIO line handle to the middle mouse button
+ - button-right-gpios: GPIO line handle to the right mouse button
+Example:
+
+#include <dt-bindings/gpio/gpio.h>
+
+gpio-mouse {
+ compatible = "gpio-mouse";
+ scan-interval-ms = <50>;
+ up-gpios = <&gpio0 0 GPIO_ACTIVE_LOW>;
+ down-gpios = <&gpio0 1 GPIO_ACTIVE_LOW>;
+ left-gpios = <&gpio0 2 GPIO_ACTIVE_LOW>;
+ right-gpios = <&gpio0 3 GPIO_ACTIVE_LOW>;

+ button-middle-gpios = <&gpio0 5 GPIO_ACTIVE_LOW>;
+ button-right-gpios = <&gpio0 6 GPIO_ACTIVE_LOW>;
