Hi Jagan,

We would like to upstream quad and dual modes(parallel and stacked) support for qspi drivers of Zynq and ZynqMP. Can we send patches based on existing framework(drivers/spi , this is what we are using on Xilinx tree) or you want us to use any other? I know we had discussion sometime back on this and we completed upstreaming driver without dual modes support as a first step. Please let me know on how to proceed further on adding quad and dual modes support. Any inputs are welcome.

Thanks, Siva

Hi Siva,

+ Boris, Miquel,

Sorry for top posting, we have spi-mem which hopefully pushed in master for this release.

So, since dual qspi is based with zynq qspi it's better write this as part of spi-mem driver.

Better to start Linux driver first so that we can get more detail how to proceed further.

Here is an example patches of DUT based fsl qspi which is supposed to be in spi-nor before [1].

Added Boris and Miquel. So they may give some inputs.
