This enables DSP IPC protocol between host AP (Linux)
|
and the firmware running on DSP.
|
DSP exists on some i.MX8 processors (e.g i.MX8QM, i.MX8QXP).
|
|
It acts like a doorbell. Client might use shared memory to
|
exchange information with DSP side.

The System Controller Firmware (SCFW) is a low-level system function
|
which runs on a dedicated Cortex-M core to provide power, clock, and
|
resource management. It exists on some i.MX8 processors. e.g. i.MX8QM
|
(QM, QP), and i.MX8QX (QXP, DX).
|
|
This driver manages the IPC interface between host CPU and the
|
SCU firmware running on M4.
