- Date: July 2018
- Contact: Heikki Krogerus <heikki.krogerus@linux.intel.com>
- Description:
- Shows if the mode is active or not. The attribute can be used
- for entering/exiting the mode. Entering/exiting modes is
- supported as synchronous operation so write(2) to the attribute
- does not return until the enter/exit mode operation has
- finished. The attribute is notified when the mode is
- entered/exited so poll(2) on the attribute wakes up.
- Entering/exiting a mode will also generate uevent KOBJ_CHANGE.
- Valid values are boolean.

- Description:
- The index number of the mode returned by Discover Modes USB
- Power Delivery command. Depending on the alternate mode, the
- mode index may be significant.

- alternate mode.
- With other alternate modes, the mode index values are not

- the mode index is not assigned, identifying the alternate mode
- must be done with either mode VDO or the description.
