Well, the debugfs stuff there is more a general tool for introspecting
the current DAPM state than it is indended to draw a pretty picture.
When I wrote it the scale of the devices I was working with was such

there's even larger devices since then (though also a lot of systems
like yours which do use very much smaller devices).
