The USB Type-C class is meant to provide unified interface to the
userspace to present the USB Type-C ports in a system.

Changes since v9:
- Minor typec_wcove.c cleanup as proposed by Guenter Roeck. No
  function affect.

Changes since v8:
- checking sysfs_streq() result correctly in sysfs_strmatch
- fixed accessory check in supported_accessory_mode
- using "none" as the only string that can clear the preferred role

Changes since v7:
- Removed "type" attribute from partners
- Added supports_usb_power_delivery attribute for partner and cable

Changes since v6:
- current_vconn_role attr renamed to vconn_source (no API changes)
- Small documentation improvements proposed by Vincent Palatin

Changes since v5:
- Only updating the roles based on driver notifications
- Added MODULE_ALIAS for the WhiskeyCove module
- Including the patch that creates the actual platform device for the
  WhiskeyCove Type-C PHY in this series.

Changes since v4:
- Remove the port lock completely

Changes since v3:
- Documentation cleanup as proposed by Roger Quadros
- Setting partner altmodes member to NULL on removal and fixing a
  warning, as proposed by Guenter Roeck
- Added the following attributes for partners and cables:
  * supports_usb_power_delivery
  * id_header_vdo
- "id_header_vdo" is visible only when the partner or cable supports
  USB Power Delivery communication.
- Partner attribute "accessory" is hidden when the partner type is not
  "Accessory".

Changes since v2:
- Notification on role and alternate mode changes
- cleanups

Changes since v1:
- Completely rewrote alternate mode support
- Patners, cables and cable plugs presented as devices.
