3 tristate "IMX DSP Protocol driver"
6 This enables DSP IPC protocol between host AP (Linux)
7 and the firmware running on DSP.
8 DSP exists on some i.MX8 processors (e.g i.MX8QM, i.MX8QXP).
10 It acts like a doorbell. Client might use shared memory to
11 exchange information with DSP side.
14 bool "IMX SCU Protocol driver"
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.

27 tristate "IMX SCMI MISC Protocol driver"
28 depends on IMX_SCMI_MISC_EXT || COMPILE_TEST
31 The System Controller Management Interface firmware (SCMI FW) is
32 a low-level system function which runs on a dedicated Cortex-M
33 core that could provide misc functions such as board control.
35 This driver can also be built as a module.
