linux-fsl 5.10 kernels don't appear to have multi-lane in sound/soc/fsl/fsl_sai.c

Hi,

First, forgive me for posting a link in an post with no context ... I hit a
wrong button and accidentally sent before ready.

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.

Regards,

Brian
