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"

+* 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;
+		};

+			      The userio Protocol
+	     (c) 2015 Stephen Chandler Paul <[e-mail]>
+			      Sponsored by Red Hat
+--------------------------------------------------------------------------------
+
+1. Introduction
+~~~~~~~~~~~~~~~
+  This module is intended to try to make the lives of input driver developers
+easier by allowing them to test various serio devices (mainly the various
+touchpads found on laptops) without having to have the physical device in front
+of them. userio accomplishes this by allowing any privileged userspace program
+to directly interact with the kernel's serio driver and control a virtual serio
+port from there.
+
+2. Usage overview
+~~~~~~~~~~~~~~~~~
+  In order to interact with the userio kernel module, one simply opens the
+/dev/userio character device in their applications. Commands are sent to the
+kernel module by writing to the device, and any data received from the serio
+driver is read as-is from the /dev/userio device. All of the structures and
+macros you need to interact with the device are defined in <linux/userio.h> and
+<linux/serio.h>.
+
+3. Command Structure
+~~~~~~~~~~~~~~~~~~~~
+  The struct used for sending commands to /dev/userio is as follows:
+
+	struct userio_cmd {
+		__u8 type;
+		__u8 data;
+	};
+
+  "type" describes the type of command that is being sent. This can be any one
+of the USERIO_CMD macros defined in <linux/userio.h>. "data" is the argument
+that goes along with the command. In the event that the command doesn't have an
+argument, this field can be left untouched and will be ignored by the kernel.
+Each command should be sent by writing the struct directly to the character
+device. In the event that the command you send is invalid, an error will be
+returned by the character device and a more descriptive error will be printed
+to the kernel log. Only one command can be sent at a time, any additional data
+written to the character device after the initial command will be ignored.
+  To close the virtual serio port, just close /dev/userio.
+
+4. Commands
+~~~~~~~~~~~
+
+4.1 USERIO_CMD_REGISTER
+~~~~~~~~~~~~~~~~~~~~~~~
+  Registers the port with the serio driver and begins transmitting data back and
+forth. Registration can only be performed once a port type is set with
+USERIO_CMD_SET_PORT_TYPE. Has no argument.
+
+4.2 USERIO_CMD_SET_PORT_TYPE
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+  Sets the type of port we're emulating, where "data" is the port type being
+set. Can be any of the macros from <linux/serio.h>. For example: SERIO_8042
+would set the port type to be a normal PS/2 port.
+
+4.3 USERIO_CMD_SEND_INTERRUPT
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+  Sends an interrupt through the virtual serio port to the serio driver, where
+"data" is the interrupt data being sent.
+
+5. Userspace tools
+~~~~~~~~~~~~~~~~~~
+  The userio userspace tools are able to record PS/2 devices using some of the
+debugging information from i8042, and play back the devices on /dev/userio. The
+latest version of these tools can be found at:
+

+ * EVIOCGMASK - Retrieve current event mask
  *
- * Most of the keys/buttons are modeled after USB HUT 1.12
- * (see http://www.usb.org/developers/hidpage).
- * Abbreviations in the comments:
- * AC - Application Control
- * AL - Application Launch Button
- * SC - System Control
+ * This ioctl allows user to retrieve the current event mask for specific
+ * event type. The argument must be of type "struct input_mask" and
+ * specifies the event type to query, the address of the receive buffer and
+ * the size of the receive buffer.
+ *
+ * The event mask is a per-client mask that specifies which events are
+ * forwarded to the client. Each event code is represented by a single bit
+ * in the event mask. If the bit is set, the event is passed to the client
+ * normally. Otherwise, the event is filtered and will never be queued on
+ * the client's receive buffer.
+ *
+ * Event masks do not affect global state of the input device. They only
+ * affect the file descriptor they are applied to.
+ *
+ * The default event mask for a client has all bits set, i.e. all events
+ * are forwarded to the client. If the kernel is queried for an unknown
+ * event type or if the receive buffer is larger than the number of
+ * event codes known to the kernel, the kernel returns all zeroes for those
+ * codes.
+ *
+ * At maximum, codes_size bytes are copied.
+ *
+ * This ioctl may fail with ENODEV in case the file is revoked, EFAULT
+ * if the receive-buffer points to invalid memory, or EINVAL if the kernel
+ * does not implement the ioctl.

+ *
+ * This ioctl is the counterpart to EVIOCGMASK. Instead of receiving the
+ * current event mask, this changes the client's event mask for a specific
+ * type.  See EVIOCGMASK for a description of event-masks and the
+ * argument-type.
+ *
+ * This ioctl provides full forward compatibility. If the passed event type
+ * is unknown to the kernel, or if the number of event codes specified in
+ * the mask is bigger than what is known to the kernel, the ioctl is still
+ * accepted and applied. However, any unknown codes are left untouched and
+ * stay cleared. That means, the kernel always filters unknown codes
+ * regardless of what the client requests.  If the new mask doesn't cover
+ * all known event-codes, all remaining codes are automatically cleared and
+ * thus filtered.
+ *
+ * This ioctl may fail with ENODEV in case the file is revoked. EFAULT is
+ * returned if the receive-buffer points to invalid memory. EINVAL is returned
+ * if the kernel does not implement the ioctl.
