I thought you were going to factor this best guess handling of peak
bandwidth out into the core?

I can centralize this for SPI, I2C and UART  in Common driver(QUP wrapper) but still for QSPI I have to keep this piece of code as is because It is not child of QUP wrapper(it doesn't use common code).

I am not sure whether I can move this " Assume peak_bw as twice of avg_bw if nothing is mentioned explicitly" to ICC core because the factor of 2 is chosen randomly by me.

Akash
