config IMX_DSP
tristate "IMX DSP Protocol driver"
depends on IMX_MBOX
help
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.
config IMX_SCU
bool "IMX SCU Protocol driver"
depends on IMX_MBOX
select SOC_BUS
help
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.
config IMX_SCU_PD
bool "IMX SCU Power Domain driver"
depends on IMX_SCU
help
The System Controller Firmware (SCFW) based power domain driver.
config IMX_SECO_MU
tristate "i.MX Security Controller (SECO) support"
depends on IMX_SCU && IMX_MBOX && MAILBOX
help
It is possible to use APIs exposed by the SECO like HSM and SHE using the
SAB protocol via the shared Messaging Unit. This driver exposes these
interfaces via a set of file descriptors allowing to configure shared
memory, send and receive messages.
