Description:
---------------------
We tried 30bpp testing on DP, but find our settings are not really worked. We
dumped the dmesg of "reboot machine and start X", then will find:
[ 186.441085] [drm:intel_modeset_pipe_config], plane bpp: 30, pipe bpp: 24,
dithering: 1
So it's not really been set to 30bpp.
Reproduce steps:
---------------------
1. modify /etc/X11/xorg.conf : DefaultDepth 30
2. reboot machine
3. xinit &
4. dmesg | grep -i "plane"</pre>
