- * struct extcon_dev - An extcon device represents one external connector.
- * @name:               The name of this extcon device. Parent device name is
- *                      used if NULL.
- * @supported_cable:    Array of supported cable names ending with EXTCON_NONE.
- *                      If supported_cable is NULL, cable name related APIs
- *                      are disabled.
- * @mutually_exclusive: Array of mutually exclusive set of cables that cannot
- *                      be attached simultaneously. The array should be
- *                      ending with NULL or be NULL (no mutually exclusive
- *                      cables). For example, if it is { 0x7, 0x30, 0}, then,
- *                      {0, 1}, {0, 1, 2}, {0, 2}, {1, 2}, or {4, 5} cannot
- *                      be attached simulataneously. {0x7, 0} is equivalent to
- *                      {0x3, 0x6, 0x5, 0}. If it is {0xFFFFFFFF, 0}, there
- *                      can be no simultaneous connections.
- * @dev:                Device of this extcon.
- * @state:              Attach/detach state of this extcon. Do not provide at
- *                      register-time.
- * @nh:                 Notifier for the state change events from this extcon
- * @entry:              To support list of extcon devices so that users can
- *                      search for extcon devices based on the extcon name.
- * @lock:
- * @max_supported:      Internal value to store the number of cables.
- * @extcon_dev_type:    Device_type struct to provide attribute_groups
- *                      customized for each extcon device.
- * @cables:             Sysfs subdirectories. Each represents one cable.
- *
- * In most cases, users only need to provide "User initializing data" of
- * this struct when registering an extcon. In some exceptional cases,
- * optional callbacks may be needed. However, the values in "internal data"
- * are overwritten by register function.
