This patch supports 32bytes of buffer for DUAL and QUAD in QSPI by
Using Transmit/Receive Buffer Data Triggering Number.
In order to improve the DUAL and QUAD's performance of SPI
while transferring data in PIO mode, it sends/receives each 32bytes
data instead of each byte data as current situation.

Nitpicking, s/rspi_pio_transfer_in_or_our/rspi_pio_transfer_in_or_out/
or am I missing something?
You're right!. It should be "rspi_pio_transfer_in_or_out"
I'll update it in an other patch.
Thanks.
