ARM : DRA7: Switch QSPI to use MODE-0 at 64MHz
According to Data Manual(SPRS915P) of AM572x, TI QSPI controller on DRA74 EVM(rev 1.1+) can support up to 64MHz in MODE-0, whereas MODE-3 is limited to 48MHz. Hence, switch to MODE-0 for better throughput. Also, add IODelay parameters for the same. Signed-off-by: Vignesh R <vigneshr@ti.com> Reviewed-by: Tom Rini <trini@konsulko.com>
