Subject: [PATCH v6 17/33] ALSA: usb-audio: qcom: Add USB QMI definitions
Date: Fri, 15 Sep 2023 17:10:10 -0700 [thread overview]
Message-ID: <20230916001026.315-18-quic_wcheng@quicinc.com> (raw)
In-Reply-To: <20230916001026.315-1-quic_wcheng@quicinc.com>
The Qualcomm USB audio offload driver utilizes the QMI protocol to
communicate with the audio DSP. Add the necessary QMI header and field
definitions, so the QMI interface driver is able to route the QMI packet
received to the USB audio offload driver.
