One side note nevertheless, check carefully existing drivers and if
your new SPI HW has small amount of differences with existing one,
better to consider unification (either using old code, or convert old
driver to use new code). I'm aware of groing Linux kernel source base
with a lot of driver duplication (at least in the past).
