215Date: July 2012
216Contact: Huang Ying <ying.huang@intel.com>
217Description:
218 d3cold_allowed is bit to control whether the corresponding PCI
219 device can be put into D3Cold state. If it is cleared, the
220 device will never be put into D3Cold state. If it is set, the
221 device may be put into D3Cold state if other requirements are
222 satisfied too. Reading this attribute will show the current
223 value of d3cold_allowed bit. Writing this attribute will set
224 the value of d3cold_allowed bit.

358 Some regulator directories will contain a field called
359 bypass. This indicates if the device is in bypass mode.

361 This will be one of the following strings:

363 'enabled'

366
367 'enabled' means the regulator is in bypass mode.

369 'disabled' means that the regulator is regulating.

371 'unknown' means software cannot determine the state, or
372 the reported state is invalid.

6 OLED mocro displays on Intuos4 Wireless tablet. Accepted image
7 has to contain 256 bytes (64x32 px 1 bit colour). The format
8 is the same as PBM image 62x32px without header (64 bits per
9 horizontal line, 32 lines). An example of setting OLED No. 0:
10 dd bs=256 count=1 if=img_file of=[path to oled0_img]/oled0_img
11 The attribute is read only and no local copy of the image is
