nrf5340 qspi for custom spi devices

[zuppiden]

Hello

Is it possible to use the qspi of the nrf5340 for custom spi devices? I need the quad spi for the 96MHz speed which the normal spi does not have.

I know of the nrfx drivers:
https://github.com/nrfconnect/sdk-hal_nordic/blob/v1.3.0-rc1/nrfx/drivers/include/nrfx_qspi.h

But are there any inputs on how to use them and how to configure Zephyr to use these drivers and the qspi?
As I know from reading through other posts here, there is no sample yet.

Thanks for any replies.

The QSPI peripherial has a fixed command set (see the PS for details) that works with some NOR flash chips, and basically nothing else.
