It looks like I need to update the binding document - I'll send a patch for that shortly. The additional property that's required to have CEC functional is a specification for calib-gpio, which must be the GPIO used for the TDA998x interrupt - you'll have to work out which GPIO that is, that's the bit I can't help with. This GPIO is used to calibrate a free running oscillator within the TDA998x used to clock the TDA9950 CEC block. -- RMK's Patch system: http://www.armlinux.org.uk/developer/patches/ FTTC broadband for 0.8mile line in suburbia: sync at 8.8Mbps down 630kbps up According to speedtest.net: 8.21Mbps down 510kbps up _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
