GXL and newer SoC's uses the DMA engine (not blkmv) for crypto HW.
Crypto HW doesn't actually use the blkmv clk. At RTL level, crypto
engine is hard weired to a clk81 (CLKID_CLK81).

Also, GXL crypto IP isn't to seconnd interrput line. So we must
remove it from dt-bindings.

Fixes: 7f7d115dfb51 ("dt-bindings: crypto: Add DT bindings
documentation for amlogic-crypto")

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.

Hi Rob,

thank you for the review.

Yep, sorry, I will fix all typos.

Yes.

I will add more clarification information in commit message in V9.

I think I have to remove clock-names field in V9.
