39 for entering/exiting the mode with partners and cable plugs, and
40 with the port alternate modes it can be used for disabling
41 support for specific alternate modes. Entering/exiting modes is
42 supported as synchronous operation so write(2) to the attribute
43 does not return until the enter/exit mode operation has
44 finished. The attribute is notified when the mode is
45 entered/exited so poll(2) on the attribute wakes up.
46 Entering/exiting a mode will also generate uevent KOBJ_CHANGE.

25Description:
26 The index number of the mode returned by Discover Modes USB
27 Power Delivery command. Depending on the alternate mode, the
28 mode index may be significant.
29
30 With some alternate modes (SVIDs), the mode index is assigned
31 for specific functionality in the specification for that
32 alternate mode.
33
34 With other alternate modes, the mode index values are not
35 assigned, and can not be therefore used for identification. When
36 the mode index is not assigned, identifying the alternate mode
37 must be done with either mode VDO or the description.

227The alternate modes will have Standard or Vendor ID (SVID) assigned by USB-IF. 227What: /sys/class/typec/<port>/<alt mode>/supported_roles
228The ports, partners and cable plugs can have alternate modes. A supported SVID
229will consist of a set of modes. Every SVID a port/partner/plug supports will
230have a device created for it, and every supported mode for a supported SVID will
231have its own directory under that device. Below <dev> refers to the device for
