I've tested this series with the DSI0 output and it works. Nice! No need for my DSI0 patch for the MT8395 anymore. But I can't get it to work with the DisplayPort output, that is the dp_intf1/dp_tx interface. I don' know how the pipeline have to look like. The functional spec seems to be ambiguous on this. The text seem to refer to the second vdosys but there is also a diagram where you can use the first vdosys and dsc0. If you have any pointers for me, I'm all ears :) -michael _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
