Please drop this commit. Adding a mdp3-mutex compatible is not needed here.

Thanks for checking. We probably would need a fallback compatible. We can only 
know from the HW engineers that can confirm if the IP block is the same as the 
disp mutex or a different one.

I'll drop both patches for now until things got clear.

Regards,
Matthias

They're located in a different iospace from each other, but either the platform
data needs to *not be* joined together, or if they're together, I would not like
having two different compatible strings for essentially the same thing.

I would at this point prefer dropping '-disp' from 'mediatek,mt8186-disp-mutex'
so that we would be able to declare two 'mediatek,mt8186-mutex' in devicetree...
...or simply have two mediatek,mt8186-disp-mutex (although logically incorrect?).

Cheers,
Angelo
