@e-rk There seems to be hypothesis that after #71989 this test fails (ie. adding in this test /delete-node/ &exmif; helps)

[e-rk]

This is because of lack of this commit: nrfconnect/sdk-zephyr@7ea6937
The commit is not suitable for upstream in this form and larger changes to the spi_dw.c will be needed.

[nordic-piks]

The same for tests/drivers/spi/spi_slave/drivers.spi_slave.api for nrf54h20dk/nrf54h20/cpuapp
