Bottom line up front.  How can I get a 5.10 kernel with multi-lane support for IMX8MM?

We use linux-fsl 5.4 on a IMXMM based board and have recently stepped up to linux-fsl 5.10 and the sound/fsl/fsl_sai.c has no support for "multi-lane" anymore which breaks our code.

I figure this is simply a case where things in linux-imx are new and just not picked up in linux-fslc yet but wondering if it's possible to get multi-lane support in a 5.10 kernel for the IMX8MM. 

I still don't quite fully understand how all the releases work, the linux-imx releases appear to be for newer boards and don't necessarily support the older boards from what I'm seeing.

Thanks for any advice/guidance.



... is the reference I mentioned where I see multi-lane support in linux-imx 5.10.
