Contact: Heikki Krogerus <[email protected]>
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.

What: /sys/bus/typec/devices/.../mode
Date: July 2018
Contact: Heikki Krogerus <[email protected]>
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.
With some alternate modes (SVIDs), the mode index is assigned
for specific functionality in the specification for that
alternate mode.
With other alternate modes, the mode index values are not
assigned, and can not be therefore used for identification. When
the mode index is not assigned, identifying the alternate mode
must be done with either mode VDO or the description.
