Maybe I don't understand the binding description then, but to me it looks like you require both port@0 and port@1. The reality of the driver is that it makes almost no use of the graph itself, except via drm_of_find_possible_crtcs() to find the connected CRTCs. If it is connected to an I2S source, then it probably needs a port specification for that. If someone wants to describe the HDMI connector (which I don't see any point in) then they likely need a port specification for that too. However, the driver itself doesn't care about any of those. So, describing the port nodes makes no sense. -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 40Mbps down 10Mbps up. Decent connectivity at last!
