-What: Compaq touchscreen device emulation
-When: Oct 2007
-Files: drivers/input/tsdev.c
-Why: The code says it was obsolete when it was written in 2001.
- tslib is a userspace library which does anything tsdev can do and
- much more besides in userspace where this code belongs. There is no
- longer any need for tsdev and applications should have converted to
- use tslib by now.
- The name "tsdev" is also extremely confusing and lots of people have
- it loaded when they don't need/use it.
-Who: Richard Purdie <rpurdie@rpsys.net>

What: i2c-ixp2000, i2c-ixp4xx and scx200_i2c drivers
When: September 2007
Why: Obsolete. The new i2c-gpio driver replaces all hardware-specific

+fail_over_mac
+
+ Specifies whether active-backup mode should set all slaves to
+ the same MAC address (the traditional behavior), or, when
+ enabled, change the bond's MAC address when changing the
+ active interface (i.e., fail over the MAC address itself).
+
+ Fail over MAC is useful for devices that cannot ever alter
+ their MAC address, or for devices that refuse incoming
+ broadcasts with their own source MAC (which interferes with
+ the ARP monitor).
+
+ The down side of fail over MAC is that every device on the
+ network must be updated via gratuitous ARP, vs. just updating
+ a switch or set of switches (which often takes place for any
+ traffic, not just ARP traffic, if the switch snoops incoming
+ traffic to update its tables) for the traditional method. If
+ the gratuitous ARP is lost, communication may be disrupted.
+
+ When fail over MAC is used in conjuction with the mii monitor,
+ devices which assert link up prior to being able to actually
+ transmit and receive are particularly susecptible to loss of
+ the gratuitous ARP, and an appropriate updelay setting may be
+ required.
+
+ A value of 0 disables fail over MAC, and is the default. A
+ value of 1 enables fail over MAC. This option is enabled
+ automatically if the first slave added cannot change its MAC
+ address. This option may be modified via sysfs only when no
+ slaves are present in the bond.
+
+ This option was added in bonding version 3.2.0.

-/* This driver emulates both protocols of the old h3600_ts and h3600_tsraw
- * devices. The first one must output X/Y data in 'cooked' format, e.g.
- * filtered, dejittered and calibrated. Second device just outputs raw

- *

- * calibration. Filtering and dejittering must be done in the low-level
- * driver, if needed, because it may gain additional benefits from knowing
- * the low-level details, the nature of noise and so on.
- *
- * The driver precomputes a calibration matrix given the initial xres and
- * yres values (quite innacurate for most touchscreens) that will result
- * in a more or less expected range of output values. The driver supports
- * the TS_SET_CAL ioctl, which will replace the calibration matrix with a
- * new one, supposedly generated from the values taken from the raw device.

+ * @getkeycode: optional method to retrieve current keymap. If not supplied
+ * default mechanism will be used
+ * @ff: force feedback structure associated with the device if device
+ * supports force feedback effects
+ * @repeat_key: stores key code of the last key pressed; used to implement
+ * software autorepeat
+ * @timer: timer for software autorepeat
+ * @sync: set to 1 when there were no new events since last EV_SYNC
+ * @abs: current values for reports from absolute axes
+ * @rep: current values for autorepeat parameters (delay, rate)
+ * @key: reflects current state of device's keys/buttons

+ * @absmin: minimum values for events coming from absolute axes
+ * @absfuzz: describes noisiness for axes
+ * @absflat: size of the center flat position (used by joydev)
+ * @open: this method is called when the very first user calls
+ * input_open_device(). The driver must prepare the device
+ * to start generating events (start polling thread,
+ * request an IRQ, submit URB, etc.)
+ * @close: this method is called when the very last user calls
+ * input_close_device().
+ * @flush: purges the device. Most commonly used to get rid of force
+ * feedback effects loaded into the device when disconnecting
+ * from it
+ * @event: event handler for events sent _to_ the device, like EV_LED
+ * or EV_SND. The device is expected to carry out the requested
+ * action (turn on a LED, play sound, etc.) The call is protected
+ * by @event_lock and must not sleep
+ * @grab: input handle that currently has the device grabbed (via
+ * EVIOCGRAB ioctl). When a handle grabs a device it becomes sole
+ * recipient for all input events coming from the device
+ * @event_lock: this spinlock is is taken when input core receives
+ * and processes a new event for the device (in input_event()).
+ * Code that accesses and/or modifies parameters of a device
+ * (such as keymap or absmin, absmax, absfuzz, etc.) after device
+ * has been registered with input core must take this lock.
+ * @mutex: serializes calls to open(), close() and flush() methods
+ * @users: stores number of users (input handlers) that opened this
+ * device. It is used by input_open_device() and input_close_device()
+ * to make sure that dev->open() is only called when the first
+ * user opens device and dev->close() is called when the very
+ * last user closes the device
+ * @going_away: marks devices that are in a middle of unregistering and
+ * causes input_open_device*() fail with -ENODEV.
+ * @dev: driver model's view of this device
+ * @h_list: list of input handles associated with the device. When
+ * accessing the list dev->mutex must be held
+ * @node: used to place the device onto input_dev_list
