DEVICE_MMIO_TOPLEVEL()

		DT_DRV_INST(3)
	)

DEVICE_MMIO_TOPLEVEL_STATIC()

DEVICE_MMIO_TOPLEVEL_STATIC	(	foo4	,

foo_mult_init()

int foo_mult_init

)

foo_single_init()

int foo_single_init

(

const struct device *

dev

)

ZTEST()

ZTEST	(	device	,

	)

device_map() test

Show that device_map() populates a memory address. We don't do anything else; tests for k_map() will prove that virtual memory mapping actually works.
