TranscoderId tied_transcoder_id ()Identifies the transcoder that is always tied to the pipe.
Each pipe has a transcoder tied to it, which can output most display
protocols (DisplayPort, HDMI, DVI). This method identifies the pipe's tied
transcoder. The return value never changes, for a given pipe.
See `connected_transcoder_id()` for identifying the transcoder that the
pipe is currently using.

TranscoderId connected_transcoder_id ()Identifies the transcoder that is currently receiving the pipe's output.
Each pipe has a tied transcoder, which can output most display protocols.
The display engine also has some specialized transcoders, which can be
connected to any pipe. The specialized transcoders are tied to DDIs that
use specialized protocols (Embedded DisplayPort, DDI), and used for writing
back to memory ("WD / Wireless Display" in Intel's docs).
This method returns the transcoder that is currently connected to the pipe
output, which can be the general-purpose transcoder tied to the pipe, or
one of the shared specialized transcoders. The return value depends on how
we configure the display engine.
bool in_use ()Defined at line 106 of file ../../src/graphics/display/drivers/intel-display/pipe.h
display::DriverConfigStamp GetVsyncConfigStamp (const std::vector<display::DriverImageId> & image_ids)Display device registers only store image handles / addresses. We should
convert the handles to corresponding config stamps using the existing
mapping updated in |ApplyConfig()|.
