Assigning pipes to a driver instance is hard as not only do we have a
limited number (so choosing which instances should share CRTCs requires
user intervention) but also some pipes are limited by hardware to
certain outputs and certain modes (and we do not have the full knowledge
of the future configuration to be able to determine where to assign the
CRTC). As usual, when there is no clear answer, punt it to the user.
This expands the ZaphodHeads option to include an optional
comma-separated pipe list followed by a colon before the output list,
e.g.
Section "Device"
Identifier "Device0"
Driver "intel"
Option "ZaphodHeads" "1:LVDS"
BusID "PCI:0:2:0"
Screen 0
EndSection
Section "Device"
Identifier "Device1"
Driver "intel"
Option "ZaphodHeads" "0,2:HDMI1,HDMI2,HDMI3"
BusID "PCI:0:2:0"
Screen 1
EndSection
