Not a big thing here as you add support for a new SoC, but the ordering 
of the patches is not optimal. Here you add the AM625 DSS support, but 
then you continue actually adding the DSS support (well, mainly OLDI) in 
the following patches.

I think patch 6 could be before this patch. Parts of patch 4 could also 
be before this patch. The AM65X renames from patch 5 could be before 
this patch.

I'm mainly thinking of a case where someone uses AM625 and is bisecting 
a problem. What happens if his board uses OLDI, and he happens to hit 
one of these patches during bisect? If the display just stays black, but 
otherwise everything works fine, then no problem. But if it crashes or 
starts spamming sync losts or such or gives errors, it's not so nice.
