We are taking care of actual throughput requirement in avg_bw vote and the

correct/improve me if this is not okay.
If this is okay, I will centralize this design for SPI QUP, I2C and UART
driver.
That seems reasonable to me, it was just the fact that every driver
seemed to be doing the same thing that I was noticing - what was being
done seemed OK.
