The naming convention is roughly <soc>-<board>.dts. For instance, in r8a7795-
h3ulcb.dts, the SoC is R8A7795 and the board "H3 ULCB". With the proposed
rename we would break that convention.
However, the name ULCB itself (which stands for Ultra Low Cost Board) might
already not follow the naming convention, as the boards are officially called
R-Car Starter Kit (Pro and Premier). The V3M and V3H "low-cost" boards reflect
that properly, with their .dts files named r8a77970-v3msk.dts and r8a77970-
v3hsk.dts respectively.
I'm not opposed to simplifying the file names, but I think we should then
decide on a simpler convention. In particular the H3/M3 and V3 .dts files
should in my opinion follow the same convention.
I'll now let others comment on this as I don't have such a strong opinion on
this topic.
