0004 Description:
0005 Shows if the mode is active or not. The attribute can be used
0006 for entering/exiting the mode. Entering/exiting modes is
0007 supported as synchronous operation so write(2) to the attribute
0008 does not return until the enter/exit mode operation has
0009 finished. The attribute is notified when the mode is
0010 entered/exited so poll(2) on the attribute wakes up.
0011 Entering/exiting a mode will also generate uevent KOBJ_CHANGE.
0012
0013 Valid values are boolean.

0025 Description:
0026 The index number of the mode returned by Discover Modes USB
0027 Power Delivery command. Depending on the alternate mode, the
0028 mode index may be significant.
0029
0030 With some alternate modes (SVIDs), the mode index is assigned
0031 for specific functionality in the specification for that
0032 alternate mode.
0033
0034 With other alternate modes, the mode index values are not
0035 assigned, and can not be therefore used for identification. When
0036 the mode index is not assigned, identifying the alternate mode
0037 must be done with either mode VDO or the description.
