OK, the steps you written is looks like a usage of driver on specific
module, my point
here was instead of placing these into driver file try to verify the
same steps on hardware
with the help of simple spi tests and place the same file on doc/SPI/ .

It's a well showed prof that this driver is working with this kind of steps.

thanks!
