USB Power Delivery has a 3 entity handshake (port, cable, partner), and as of USB PD R3.0, each entity may independently support either Revision 2 or Revision 3 signaling and protocol. In order for userspace and the kernel to properly process the data objects received from a particular SOP*, we must know to which revision of the spec each conforms. This series adds individual version numbers for the partner and the cable, and exposes them in the appropriate sysfs in /sys/class/typec. I provide as a first implementation of this, platform/chrome's cros_ec_typec driver, whose underlying status messages convey the SOP and SOP' revisions already.
