Felipe, Question about the patch[1]. I want to change the code in a way to not touch fifo thresholds for each message. Because: 1. dev->threshold is valid only with checking of transfer direction. So, if last transfer was transmission and ISR get RRDY interrupt from slave receiver, then dev->threshold is invalid. We must read threshold value from BUF register, to process correctly. 2. I want to avoid changing fifos before message submission, because IP can start receiving message in a slave mode (race). 3. dev->threshold is changed in range 1-fifo_size/2. So instead of RDR we get RRDY and for messages larger then fifo_size/2 we still get RRDY and RDR. Felipe, do you have in mind why do you want to avoid RDR and XDR events? Something about errata?
