Same here. I don't need Ravi's patch for the INTx bit enabling. I understand that you want us to change the interrupt map in the auto- generated device-tree from Vivado. Which is IMHO a bit "suboptimal". I would prefer to have a solution which works out-of-the-box, w/o the need to manually change DT properties. Is it planned to change / fix this interrupt map in pl.dtsi generated with a newer version of Vivado? Thanks, Stefan
