CT CP? HPD is obviously the hotplug detect signal, but why are there two - HDMI only has a single detect pin on the connector. While it makes sense to stick all three into one property, is it possible that not all of these may be routed to a GPIO? If so, how do you specify that one (or more) of these does not exist? Another issue here is that other HDMI encoders are available - should every encoder define its own set of bindings, or should there be a base set of bindings which all encoders should conform to - such as always having a HDMI output port? -- FTTC broadband for 0.8mile line: now at 9.7Mbps down 460kbps up... slowly improving, and getting towards what was expected from it. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
