What we do on Marvell platforms is:
marvell,spi-base = <128>, <136>, <144>, <152>;
see marvell,odmi-controller.txt.
In another driver I submitted, we're doing:
marvell,spi-ranges = <64 64>, <288 64>;
Retrospectively, I would have preferred to use marvell,spi-ranges for
the first DT binding as well, since it allows to express both the base
and number of interrupts available in the range.
Best regards,
Thomas
