18	  The System Controller Firmware (SCFW) is a low-level system function
19	  which runs on a dedicated Cortex-M core to provide power, clock, and
20	  resource management. It exists on some i.MX8 processors. e.g. i.MX8QM
21	  (QM, QP), and i.MX8QX (QXP, DX).

23	  This driver manages the IPC interface between host CPU and the
24	  SCU firmware running on M4.
