Just finished working with kuogee on this. This issue had been reported 
by few others earlier (example 
https://lore.kernel.org/lkml/bc9be279-a130-d5e7-4397-bbb389d14403@intel.com/T/).

So let me summarize the fix:

1) We do need up upgrade the dtschema first

pip3 install git+https://github.com/devicetree-org/dt-schema.git@main

2) Python version issues were hitting some of the developers so even if 
we had the right version installed the PATH wasnt pointing to the right one

3) We had to install yamllint

We have documented these now for the benefit of others internally.

With all these 3 done, we can compile msm-next-lumag using
make dt_binding_check DT_SCHEMA_FILES=display/msm

Apologies for the setup issues on our end. These are resolved now and 
kuogee will post a v12 for this.

Thanks
