I'm not reading 1000s of lines of driver code to figure it out, what
differs in the programming model for these two devices? You should
mention in your commit message why the cv1810 has an incompatible
programming model if you are adding multiple devices in one commit
message.

This could just be "maxItems: 1".

You have one clock, why do you need a name?

Otherwise, this looks okay, thanks.

In fact, they have no different in the programming model. The only
different between them is that cv1810 have one extra clock.

OK, I will

I am not pretty familiar with this. I just wrote this binding by
referencing others. Maybe use "maxItems: 1" is just fine?

I have referenced this name in the clk_parent_data as the global clock
parent. Removing this will cause driver broken.

With more and more sophgo products coming, I suggest add one subfolder 
"sophgo" for sophgo clock drivers, and this is what I am doing for 
sg2042, you can have a look of my patch.

Can you share some more convincing reasons? Otherwise, I suggest you may
change your file path. I have not noticed anyone doing this except sifive.
And I still have some doubt on this.
