I redo the bisect and get the following result; 
# first bad commit: [a314f6367787ee1d767df9a2120f17e4511144d0] mtd: spi-nor: Convert cadence-quadspi to use spi-mem framework

It contains significant amount of changes;

cadence-quadspi.c |  476 +++++++++++++++++++++---------------------------------
 1 file changed, 191 insertions(+), 285 deletions(-)

With this change, cpspi_probe return 0 without any error messages, but it does not detect NOR flash on a custom cyclone V board. 

Any information will be appreciated.

Thanks,
