[PATCH v3 0/8] Add the Quadspi driver for vf610-twr

? 2013?09?16? 19:06, Mark Brown ??:

I don't know what you mean by "the dummy".

Please see the datasheet of the NOR:
www.spansion.com/Support/Datasheets/S25FL128S_256S_00.pdf


Please see the page 100, the Quad I/O Read, the figure 10.37 shows
the dummy.

The dummy is just a delay in a command sequence.
The dummy maybe only several clock cycles, less then 8 bit.

thanks
