Nah, the existing convention is "LS7Xxxxx" for bridges and "Loongson 
3Axxxx" for CPUs (SoCs like 2K fall under this category too). It's 
better to stick with existing practice so it would be familiar to 
long-time Loongson/LoongArch developers, but I personally don't think it 
will hamper understanding if you feel like doing otherwise.
