+     * Set a device port of an external device into connected state.
+     *
+     * This method is used to inform the HAL module that an external device has
+     * been connected to a device port selected using the 'id' field of the
+     * input AudioPort parameter. This device port must have dynamic profiles
+     * (an empty list of profiles). This port is further referenced to as "port
+     * template" because it acts as a template for creating a new instance of a
+     * "connected" device port which gets returned from this method.
+     *
+     * The input AudioPort parameter may contain any additional data obtained by
+     * the system side from other subsystems. The nature of data depends on the
+     * type of the connection. For example, for point-to-multipoint external
+     * device connections, the input parameter may contain the address of the
+     * connected external device. Another example is EDID information for HDMI
+     * connections (ExtraAudioDescriptor), which can be provided by the HDMI-CEC
+     * HAL module.
+     *
+     * It is the responsibility of the HAL module to query audio profiles
+     * supported by the connected device and return them as part of the returned
+     * AudioPort instance. In the case when the HAL is unable to query the
+     * external device, an error must be thrown.
+     *
+     * Thus, the returned audio port instance is the result of combining the
+     * following information:
+     *  - a unique port ID generated by the HAL module;
+     *  - static information from the port template;
+     *  - list of audio profiles supported by the connected device;
+     *  - additional data from the input AudioPort parameter.
+     *
+     * The HAL module must also update the list of audio routes to include the
+     * ID of the instantiated connected device port. Normally, the connected
+     * port allows the same routing as the port template.
+     *
+     * Also see notes on 'ModuleDebug.simulateDeviceConnections'.
+     *
+     * The following protocol is used by HAL module client for handling
+     * connection of an external device:
+     *  1. Obtain the list of device ports and their IDs via 'getAudioPorts'
+     *     method. Select the appropriate port template using
+     *     AudioDeviceDescription ('ext.device' field of AudioPort).
+     *  2. Combine the ID of the port template with any additional data and call
+     *     'connectExternalDevice'. The HAL module returns a new instance of
+     *     AudioPort created using the rules explained above. Both
+     *     'getAudioPort' and 'getAudioPorts' methods will be returning the same
+     *     information for this port until disconnection.
+     *  3. Configure the connected port with one of supported profiles using
+     *     'setAudioPortConfig'.
+     *  4. Query the list of AudioRoutes for the new AudioPort using
+     *     'getAudioRoutesForAudioPort' or 'getAudioRoutes' methods.
+     *
+     * External devices are distinguished by the connection type and device
+     * address. Calling this method multiple times to inform about connection of
+     * the same external device without disconnecting it first is an error.
+     *
+     * The HAL module must perform validation of the input parameter and throw
+     * an error if it is lacking required information, for example, when no
+     * device address is specified for a point-to-multipoint external device
+     * connection.
+     *
+     * Handling of a disconnect is done in a reverse order:
+     *  1. Reset port configuration using the 'resetAudioPortConfig' method.
+     *  2. Release the connected device port by calling the 'disconnectExternalDevice'
+     *     method. This also removes the audio routes associated with this
+     *     device port.
+     *
+     * @return New instance of an audio port for the connected external device.
+     * @param templateIdAndAdditionalData Specifies port template ID and any

+# Remote Provisioning Changelog
+
+This document provides an exact description of which changes have occurred in the
+`IRemotelyProvisionedComponent` HAL interface in each Android release.
+
+## Releases
+* **Android S (12):** IRemotelyProvisionedComponent v1
+* **Android T (13):** IRemotelyProvisionedComponent v2
+
+## IRemotelyProvisionedComponent 1 -> 2
+* DeviceInfo
+ * Most entries are no longer optional.
+ * `att_id_state` is now `fused`. `fused` is used to indicate if SecureBoot is enabled.
+ * `version` is now `2`.
+ * `board` has been removed.
+ * `device` has been added.
+* RpcHardwareInfo
+ * `uniqueId` String added as a field in order to differentiate IRPC instances on device.

+     * must be removed first, and then the AP interface can be created after
+     * the STA has been torn down. During this process the remaining STA and NAN
+     * interfaces must not be removed/recreated.
