+* 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 <thatslyude@gmail.com>
+			      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.

+ * EVIOCSMASK - Set event mask
+ *
+ * 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.
