There's no end to early morning link-up — whatever you want! (3,4,2)
I believe the answer is:
you name it
'whatever you want' is the definition.
(I've seen this before)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for you name it that I've seen before include "asked of vicar at font" , "It's your eponym" , "What happens to a baby at a christening?" , "whatever's needed" , "solver chooses!" .)
