This patchset depends on "[PATCH 0/3] Add Samsung S6D7AA0 panel 
controller driver" for the display panel support for the Samsung Galaxy 
3 8.0 boards.

Ah, that makes sense. I'll re-send the patchset in a second with the 
panel node removed.

The dependency display panel patchset introduces the panel and its 
bindings, which in turn are included in the Tab3 DTSI. It was submitted 
at roughly the same time as this series, and hasn't been fully reviewed 
or merged as of writing. (I have seen your comments on that patchset, 
and I will be addressing them shortly.) So the bindings haven't been 
explicitly ACKed yet (assuming you mean the Acked-by reply).

In response to:

 > Please rework your patchsets to remove any of such dependencies.

I suggested that I could remove the panel node from the DTSI for the 
time being. The intent was to submit it in a separate patch later, once 
the display is reviewed/merged, and thus actually available in the 
kernel; this way, the two patches could be reviewed and merged separately.

I could instead wait for the display patchset to get reviewed/merged 
first, then resubmit this series, if that's preferable.

I apologize for the confusion.

Artur Weber
