The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option
is used to configure any non-standard kernel with a much larger scope than
only small devices.This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
references to the option throughout the kernel. A new CONFIG_EMBEDDED
option is added that automatically selects CONFIG_EXPERT when enabled and
can be used in the future to isolate options that should only be
considered for embedded systems (RISC architectures, SLOB, etc).Calling the option "EXPERT" more accurately represents its intention: only
expert users who understand the impact of the configuration changes they
are making should enable it.Reviewed-by: Ingo Molnar

Currently hid doesn't export the features it knows to the specific modules.
Some information can be really important in such features: MosArt and
Cypress devices are by default not in a multitouch mode.
We have to send the value 2 on the right feature.This patch exports to the module the features report so they can find the
right feature to set up the correct mode.Signed-off-by: Benjamin Tissoires

So far the USBLED driver only supports Delcom's "USB Visual Signal
Indicator" (http://www.delcomproducts.com/products_USBLMP.asp). The
driver generates virtual files "red", "green", and "blue" under the
device's /sys/ directory, where color values can be read from and
written to.This patch adds support for Dream Cheeky's "DL100B Webmail Notifier"
(http://www.dreamcheeky.com/webmail-notifier -- available from several
shops, such as http://www.conrad.at/ce/de/product/777048/USB-WEBMAIL).
This device isn't as pretty as Delcom's, but it's *far* cheaper, and
its 3 LEDs can be set in 32 brightness steps each. The grey envelope
contour can easily be removed, leaving a rather neutral white box (with
a few small holes), which is useful for generic signalling purposes.
Of course, the small circuit board can easily be put into a prettier
case.The DL100B device pretends to be a HID, but the HID descriptor shows
that it's not overly useful as such (see below). The patch therefore
removes the "HID-ness" (hid-core.c, hid-ids.h), and adds the necessary
commands to usbled.c. The protocol info comes from the developer's
manual that Dream Cheeky kindly provided (815DeveloperManual.pdf).HID descriptor:
0: 05 01 Usage Page 'Generic Desktop Controls'
2: 09 10 Usage 'Reserved'

The firmware in the joojoo reports touches sequentially, one per
report, which confuses the current driver. A further complication is
the absense of any indication of a touch frame. This patch converts
the driver to the MT slots protocol, and outputs one full touch frame
per report. This way, proper handling for both firmwares is ensured.Tested-by: Philipp Merkel

The drivers using the type B protocol all report tracking information
the same way. The contact id is semantically equivalent to
ABS_MT_SLOT, and the handling of ABS_MT_TRACKING_ID only complicates
the driver. The situation can be improved upon by providing a common
pointer emulation code, thereby removing the need for the tracking id
in the driver. This patch moves all tracking event handling over to
the input core, simplifying both the existing drivers and the ones
currently in preparation.Acked-by: Ping Cheng

The device has 2 modes. The first one is an emulation of a touchscreen
by sending left and right button, and the second mode is the one used in
dual-touch (sending trackingID, touch and else).In case of a suspend/resume, the device switch back to the first mode
described above (with left and right buttons).
This adds a hook in .reset_resume for the device to be switched to

This commit allows the device to be recognized as a touchscreen, and not a
touchpad by xf86-input-evdev.The device has 2 modes. The first one is an emulation of a touchscreen by
sending left and right button, and the second mode is the one used in
dual-touch (sending trackingID, touch and else).That's why there is a hid report containing left and right buttons
(9000001 and 9000002). The point is that xorg relies on these fields to
determine if it's a touchpad or a touchscreen.
Clearing the report (return -1) makes xorg detecting it out of the box
as a quite pleasant (dual)touchscreen.Signed-off-by: Benjamin Tissoires
