Also, you can remove the #ifdef here and the of_match_ptr() below.
If this is removed, then I'll have to add the OF dependency in the Kconfig,
correct?
I believe it will still compile without the CONFIG_OF dependency, but
having the dependency still makes sense as it's impossible to use the
driver without CONFIG_OF.

The best dependency line is probably

	depends on (ARCH_MSM && OF) || COMPILE_TEST"

If you expect the same driver to be used on non-MSM platforms from
qualcomm, e.g. some networking or server equipment, you can also just
drop the ARCH_MSM dependency.

Thanks for the clarification.  I think I'll probably do:
ARCH_MSM_DT || (COMPILE_TEST && ARM)

The latter due to my use of writel_relaxed.
