Subject: HID: make 3M PCT touchscreen driver standalone config option

The point behind 'default !EMBEDDED' for certain HID drivers that simple and
straightforward quirks for HID devices (which are implemented as drivers on
HID bus) wouldn't have to be enabled separately, if the device is otherwise
more-or-less HID standard compliant.

But this driver is rather standalone driver, so we'd want to have it normally
selectable.

From: Jiri Kosina <jkosina@suse.cz>
Date: Mon, 4 Jan 2010 12:04:59 +0100
Subject: HID: make Stantum driver standalone config option

Analogically to commit "HID: make 3M PCT touchscreen driver
standalone config option", remove the dependency of Stantum
driver on CONFIG_EMBEDDED, as it is a standalone driver rather
than device quirk.

Subject: HID: add driver for the Logitech Flight System G940

Implements a new USB-HID for Force Feedback based on the normal
Logitech Force Feedback code and FF-Memless.

Currently only supports the FF_CONSTANT effect although the joystick
appears to support additional non-standard ones.

Subject: HID: make full-fledged hid-bus drivers properly selectable

For historical reasons, we don't have most of the in-tree
drivers residing on hid-bus properly selectable in kernel
configuration unless CONFIG_EMBEDDED is set.

This has been introduced on Linus' request from 14 Oct

===
As to the Kconfig options - do they really add so much space that you need to
ask for the quirks? You didn't use to. Can you make the questions depend on
EMBEDDED, or at least on the HID_COMPAT thing or whatever?
===

This still makes perfect sense for small and tiny drivers, which
just fix report descriptors, fix up HID->input mappings that slightly
violates HUT standard, send one extra packet to the device that is
needed before it becomes functional, etc.

Since then, we have been gathering more and more HID-bus drivers,
which are full-fledged drivers. For these, the size argument becomes
more valid. Plus the devices are much more special than "just violates
HID specification in this one or two tiny unimportant points".

Therefore I am marking such drivers as properly selectable no matter
the setting of CONFIG_EMBEDDED, while keeping all the small and tiny
ones compiled by default.

From: Michael Poole <mdpoole@troilus.org>

Subject: HID: add a device driver for the Apple Magic Mouse.

The Magic Mouse requires that a driver send an unlock Report(Feature) command,
similar to the Wacom wireless tablet and Sixaxis controller quirks.  This turns
on an Input Report that isn't published in the input Report descriptor that
contains touch data (and usually overrides the normal motion and click Report).

Because the mouse has only one switch and no scroll wheel, the driver
(under control of parameters) emulates a middle button and scroll wheel.
User space could also ignore and/or re-synthesize those events based on
the reported events.

Some user-space tools to talk to the mouse directly (that is, when it is not
associated with the host's HIDP stack) are at
http://github.com/entrope/linux-magicmouse

Subject: HID: fix up Kconfig entry for MagicMouse

Make Apple MagicMouse Kconfig entry consistent with other dirvers.
Also expand the tristate text a little bit more, so that it doesn't
clash with already existing HID_APPLE.
