 Are these two still #if defined needed?

 Also, what about the IS_DEFINED macro?
Yes. To avoid the build break in !DT build.
No, infact of_match_ptr is there just so you can avoid a
#ifdef around and not break !CONFIG_OF.

Need to recheck but the build was throwing error becasue of
"emif_of_match"
mostly.

You still need the first one. I meant the second one around
'of_match_ptr' should be removed.

With !CONFIG_OF, of_match_ptr(_ptr) is just defined as NULL.
Yep. That make sense too.
Will drop the second check.
Posted the entire series again with updated $subject patch.
With your ack, I will ask Tony to pull this series for 3.6.
Sent them where?  I didn't see a copy here :(
Hi Greg, should have hit both linux-omap and linux-arm. See:
