Yes, I'm planning exactly that. I just wanted to get everything more or
less working so that the SandyBridge changes are more obvious before
reworking everything. I was thinking about making the whole device a
class that then knows about its registers and possibly add further
objects abstracting the planes, pipes and transcoders if it makes sense.
Since we're now looking at analog, HDMI, LVDS, DP and embedded DP, some
form of abstraction will be necessary to support even my setup
correctly. Right now it basically sets the mode using the analog code
path even though it's actually an eDP or LVDS panel that just happens
to be on transcoder A...
