+Date:		July 2012
+Contact:	Huang Ying <ying.huang@intel.com>
+Description:
+		d3cold_allowed is bit to control whether the corresponding PCI
+		device can be put into D3Cold state.  If it is cleared, the
+		device will never be put into D3Cold state.  If it is set, the
+		device may be put into D3Cold state if other requirements are
+		satisfied too.  Reading this attribute will show the current
+		value of d3cold_allowed bit.  Writing this attribute will set
+		the value of d3cold_allowed bit.

+Description:
+		The /sys/class/hidraw/hidraw*/device/oled*_img files control
+		OLED mocro displays on Intuos4 Wireless tablet. Accepted image
+		has to contain 256 bytes (64x32 px 1 bit colour). The format
+		is the same as PBM image 62x32px without header (64 bits per
+		horizontal line, 32 lines). An example of setting OLED No. 0:
+		dd bs=256 count=1 if=img_file of=[path to oled0_img]/oled0_img
+		The attribute is read only and no local copy of the image is
+		stored.
