The for-next branch contains changes intended to go upstream in the next merge 
window. So, yes, that's where you find the new stuff.

I guess that some of the i.MX51 peripherals are either identical or very close 
to those found in earlier i.MX chips, which already have drives in the 
mainline kernel. The only sure way to know which one works is to look at the 
chip Reference Manual, compare to the actual driver code, and test.
