+
+description: |
+  Qualcomm Messaging Interface (QMI) is an interface that clients can
+  use to send, and receive, messages from a remote entity. The coresight
+  QMI component is to configure QMI instance ids and service ids for different
+  remote subsystem connections. Coresight QMI driver uses the ids to init
+  the qmi connections. Other coresight drivers call the send qmi request
+  function when connection is established.
