Thanks, I think this is legit. It was introduced with:

commit f52cdcce9197fef9d4a68792dd3b840ad2b77117
Author: Daniel Baluta <daniel.baluta@nxp.com>

firmware: imx: Allow IMX DSP to be selected as module

IMX DSP is only needed by SOF or any other module that
wants to communicate with the DSP. When SOF is build
as a module IMX DSP is forced to be built inside the
kernel image. This is not optimal, so allow IMX DSP
to be built as a module.

So, I think we should change the Fixes tag. Are there
any clear rules on when to use select vs depends?

On my side, I know what both are doing but it is not clear
when to use them.
