typo.

2 more typos. Spell checkers exist. Use them instead of me please.

I think you forgot the word 'connected' too.

So did this binding not work at all? Are there any users? You need a bit 
more justification for an ABI breaking change.

This line should not be wrapped.

Drop the blank line.

Clocks are supposed be named local to the block like what function or 
part of the block they clock. This sounds like something global. 

With only 1 clock, I'd just drop the name altogether.
