title: Qualcomm coresight QMI(Qualcomm Messaging Interface) component

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.
