The same port/endpoint bindings are used by Philipp Zabel in his > imx-drm patch series. This series is a piece of bigger series, which brings DT support for OMAP display subsystem. This uses the same V4L2 style ports/endpoints as has been discussed recently regarding the series from Philipp. It doesn't use the helper code from Philipp, but a custom one as Philipp's code didn't exist when I made this, and also because I needed extra functionality not present in Philipp's series (which aimed to just move the current V4L2 code to a common place). The main concerns with the ports/endpoints has been the optional 'port' node for the case where we have a single endpoint, and the double-linking of the endpoints. If I remove the optional 'port' usage from my series, are you ok with me proceeding with this series for 3.15, with the double-linked endpoints? As far as I see, when we come to a conclusion how the linking should be made, it's trivial to change the bindings in this series to match it, even without needing any compatibility code. I just need to remove the other link, and old dts files having double-linking will still work fine. The reason I want to push this forward asap is that omap4 and omap5 are already DT only, and for omap5 we don't have working display without DT support for display. For omap4, we have a really hacky way to add display support for a few boards, but that is causing major headaches and I want to get rid of it. Tomi
