dmesg after run case "testdisplay -i "&"testdisplay -a"
Environment:
-------------------
Kernel: (drm-intel-next-queued) 4c0e552882114d1edb588242d45035246ab078a0
Hardware name: Apple Inc. MacBookPro10,2/Mac-AFD8A9D944EA4843,
BIOS MBP102.88Z.0106.B03.1211161133 11/16/2012
Description:
------------------------
When Apple boot up with eDP and miniDP-to-DP connected, the eDP monitor can be
lighted up correctly, while the DP monitor was black without any output.
But when I run case "testdisplay -i", it shows:

And when I run case "testdisplay -a", the DP monitor can show all modes
correctly.
After I start X, the eDP can show the X window correctly , but the DP can't
either.
Test Step:
--------------------
1. connect miniDP-to-DP
2. Boot up
3. testdisplay -i
4. testdisplay -a</pre>
