From 5d7e7d479856f23eebc272128905a7ecada367fb Mon Sep 17 00:00:00 2001 From: Eduard Hasenleithner Date: Wed, 7 Sep 2011 14:08:54 -0700 Subject: 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 Signed-off-by: Eduard Hasenleithner Signed-off-by: Dmitry Torokhov --- Documentation/ABI/testing/sysfs-driver-wacom | 64 ++++++++++++++++++++++++++++ Documentation/ABI/testing/sysfs-wacom | 10 ----- 2 files changed, 64 insertions(+), 10 deletions(-) create mode 100644 Documentation/ABI/testing/sysfs-driver-wacom delete mode 100644 Documentation/ABI/testing/sysfs-wacom (limited to 'Documentation/ABI') diff --git a/Documentation/ABI/testing/sysfs-driver-wacom b/Documentation/ABI/testing/sysfs-driver-wacom new file mode 100644 index 000000000000..dfe1d460cf54 --- /dev/null +++ b/Documentation/ABI/testing/sysfs-driver-wacom @@ -0,0 +1,64 @@ +What: /sys/class/hidraw/hidraw*/device/speed +Date: April 2010 +Kernel Version: 2.6.35 +Contact: linux-bluetooth@vger.kernel.org +Description: + The /sys/class/hidraw/hidraw*/device/speed file controls + reporting speed of Wacom bluetooth tablet.
