Looking at drivers/pci/controller/dwc/Kconfig,
there are a lot of:

depends on OF && (ARM64 || COMPILE_TEST)

So I think Vidya simply followed this pattern and instead did:
depends on ARCH_TEGRA && (ARM64 || COMPILE_TEST)


But, since we don't have an explicit "depends on OF"
in these entries, I do think that:

depends on (ARCH_TEGRA && ARM64) || COMPILE_TEST

is slightly more correct. (Since if there was a hard requirement on OF,
it would have been there already).


Kind regards,
