Why constantly wait on interrupts to then swap back to the calling thread to then update a few registers? This is a lot of extra work that really isn't needed in this driver.

Make the driver a simple state machine that reads/writes out of a current transfer and wait for completion of the whole thing? any particular reason to have a k_sem_take in a for loop wait on byte at a time transfers?

Hi @teburd

I try to make driver work without IRQ, I was not able to get it working stable enough. Most likely because I am trying to fetch status reg all the time. Instead of write bit on the first transmit with that approach bit is converted to read , keep in mind the driver flow was not touched , neither command setting up the peripheral etc. I am guessing reason is kind of race condition or something like that. All drivers for TI CCXXXX chips have the same driver structure. If we agree it is not critical I will prefer to keep it like that for now.

Just rebased again on latest main , because of merged PR for the same platform.
