Hi Frank,

The code to handle this is already upstream and used for:

Remoteproc

https://elixir.bootlin.com/linux/v6.12/source/drivers/remoteproc/imx_dsp_rproc.c#L991

and Sound Open Firmware

https://elixir.bootlin.com/linux/v6.12/source/sound/soc/sof/imx/imx8m.c#L237

I'm not sure if it worths the effort to refactor this for such a
simple operation.
