+/**
+ * Camera provider HAL, which enumerates the available individual camera devices
+ * known to the provider, and provides updates about changes to device status,
+ * such as connection, disconnection, or torch mode enable/disable.
+ *
+ * The provider is responsible for generating a list of camera device service
+ * names that can then be opened via the hardware service manager.
+ *
+ * Multiple camera provider HALs may be present in a single system.
+ * For discovery, the service names, and process names, must be of the form
+ * "android.hardware.camera.provider@<major>.<minor>/<type>/<instance>"
+ * where
+ *   - <major>/<minor> is the provider HAL HIDL version,
+ *   - <type> is the type of devices this provider knows about, such as
+ *     "internal", "legacy", "usb", or "remote"
+ *   - <instance> is a non-negative integer starting from 0 to disambiguate
+ *     between multiple HALs of the same type.
+ *
+ * The "legacy" type is only used for passthrough legacy HAL mode, and must
+ * not be used by a standalone binderized HAL.
+ *
+ * The device instance names enumerated by the provider must be of the form
+ * "device@<major>.<minor>/<type>/<id>" where
+ * <major>/<minor> is the HIDL version of the interface. <id> is either a small
+ * incrementing integer for "internal" device types, with 0 being the main
+ * back-facing camera and 1 being the main front-facing camera, if they exist.
+ * Or, for external devices such as type "usb", a unique serial number that can
+ * be used to identify the device reliably when it is disconnected and
+ * reconnected. Multiple providers may not enumerate the same device ID.
