The newly added SCMI vendor driver references functions in the protocol driver but needs a Kconfig dependency to ensure it can link, essentially the Kconfig dependency needs to be reversed to match the link time dependency: | arm-linux-gnueabi-ld: sound/soc/fsl/fsl_mqs.o: in function `fsl_mqs_sm_write': | fsl_mqs.c:(.text+0x1aa): undefined reference to `scmi_imx_misc_ctrl_set' | arm-linux-gnueabi-ld: sound/soc/fsl/fsl_mqs.o: in function `fsl_mqs_sm_read': | fsl_mqs.c:(.text+0x1ee): undefined reference to `scmi_imx_misc_ctrl_get' This however only works after changing the dependency in the SND_SOC_FSL_MQS driver as well, which uses 'select IMX_SCMI_MISC_DRV' to turn on a driver it depends on. This is generally a bad idea, so the best solution is to change that into a dependency. To allow the ASoC driver to keep building with the SCMI support, this needs to be an optional dependency that enforces the link-time dependency if IMX_SCMI_MISC_DRV is a loadable module but not depend on it if that is disabled.

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.

The System Controller Management Interface firmware (SCMI FW) is

a low-level system function which runs on a dedicated Cortex-M

core that could provide misc functions such as board control.
|

This driver can also be built as a module.
