[Intel-gfx] [RFC Patch 0/3] DRM/I915: Use the child device array to decide whether the given HDMI/DP should be initialzied

From: Zhao Yakui <yakui.zhao at intel.com>

On some boxes(for example: the laptops based on G4X platform) there is no
HDMI/DP output port. But the corresponding HDMI/DP output will be initialized
and there status is disconnected. It is confusing.
This patch set uses the child devices parsed from VBT to decide whether
the given HDMI/DP should be initialized.
If the given HDMI/DP can't be found in the child device array, it won't be 
initialized.

I also test this patch set on several boxes based on G4x platform. And it
can work well.

Welcome the comments.
