Benjamin Tissoires c704b4ef1a Input: wacom - update the ABI doc according to latest changes
Now the devices show up under hid no matter the connection (for USB
and Bluetooth, not serial nor i2c).

The USB devices can now be easily found under
/sys/bus/hid/devices/<bus>:<vid>:<pid>.<n>

The Bluetooth devices could also be found under this path since their
inclusion (April 2010), so this patch fixes the non-precise "hidraw*" path
for them.

The ABI has been unified while setting the LEDs and OLEDs. So Bluetooth
devices lost their own LED selector but use the USB sysfs attribute.
For OLEDs, Bluetooth devices handle only 1-bit images instead of 4 for USB.
The documentation has been updated to match this.

Przemo Firszt e3c399ee4a HID: wacom: OLEDs control over sysfs for Intuos4
Thsi patch adds ability to control OLED micro displays on Wacom Intuos4
Wireless. The OLEDS are exposed as
/sys/class/hidraw/hidraw*/device/oled{No]_img
where No. is 0 to 7

Setting an image:

dd bs=256 if=img_file of=/sys/class/hidraw/hidraw{No}/device/oled0_img

The image has to contain 256 bytes (64x32px 1 bit). More detailed
description in Documentation/ABI/testing/sysfs-driver-wacom

Linus Torvalds 2c01e7bc46 Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input
Pull input layer updates from Dmitry Torokhov:
 - a bunch of new drivers (DA9052/53 touchscreenn controller, Synaptics
   Navpoint, LM8333 keypads, Wacom I2C touhscreen);
 - updates to existing touchpad drivers (ALPS, Sntelic);
 - Wacom driver now supports Intuos5;
 - device-tree bindings in numerous drivers;
 - other cleanups and fixes.

Fix annoying conflict in drivers/input/tablet/wacom_wac.c that I think
implies that the input layer device naming is broken, but let's see.  I
brough it up with Dmitry.

Przemo Firszt d13f5454e4 HID: wacom: Add LED selector control for Wacom Intuos4 WL
Add sysfs attribute to control LED selector on Wacom Intuos4. There are 4
different LEDs on the tablet and they can be turned on by something like:

echo 50 > /sys/class/leds/(device # here)\:selector\:1/brightness

Only one can be lit at a time. The brightness range is 0 to 127. This patch
also contains short ABI description.

Jason Gerecke 9b5b95dd51 Input: wacom - add Intuos5 Touch Ring LED support
The Touch Ring LEDs on Intuos5 tablets use a different report
format which supports only 4 levels of brightness. We remap
the 7-bit value obtained from sysfs to an appropriate value
for the tablet. Control of the crop mark LEDs (new to the I5)
is left for a later patch.

Jason Gerecke 246835fccd Input: wacom - add LED support for Cintiq 24HD
The Cintiq 24HD has three LEDs on the left side of the tablet and
three LEDs on the right side of the tablet. Switching to LED 0,
1, or 2 will enable the top, middle, or bottom LED for the respective
side. Switching to LED 3 turns off the LEDs on the respective side.

Eduard Hasenleithner 5d7e7d4798 Input: wacom - add Intuos4 LED and OLED control
This commit enables control of the LEDs and OLED displays found on the
Wacom Intuos4 M, L, and XL. For this purpose, a new "wacom_led" attribute
group is added to the sysfs entry of the USB device.

This "wacom_led" group only shows up when the correct device (M, L, or XL)
is detected. The attributes are described in
 Documentation/ABI/testing/sysfs-wacom
