Hi Biju, > Wolfram, Can you please confirm transmit end interrupt handler worked for you > with the commit 4c84c1b3acca ("ARM: shmobile: r7s72100: add scif nodes to dtsi") That was nearly 10 years ago :) I can't recall if a specific interrupt worked. But SCIF worked. So, if it was needed for proper operation, then it probably worked. If it was not needed, no idea. This is all for a Fixes: tag, or? Is it that important? Happy hacking, Wolfram
