Should it be moved into bridge/ ? It isn't implemented as a DRM bridge driver at present, so this seems illogical. Is the longer term plan to convert it to be a DRM bridge? Secondly, if you want HDMI audio support, you may find the patches I maintain for the SolidRun devices useful, which add this as a standard ALSA device. I also have CEC support for it as well. If you're interested, I'll email those. -- FTTC broadband for 0.8mile line: currently at 9.5Mbps down 400kbps up according to speedtest.net. -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
