The location of a file may not be suitable because of xxx_driver under arch/arm/mach-*. ---diff --git a/arch/arm/mach-tegra/Makefile b/arch/arm/mach-tegra/Makefile
Russell, Olof, Arnd, Where should this driver be placed? It's a completely Tegra-specific module, and I don't believe there's any drivers/ directory or other subsystem that's appropriate to house it right now. Should we go ahead and create a drivers/arm/ for this? Perhaps drivers/misc/? Honestly, to me it seems best to keep purely platform-specific drivers like this in arch/arm/mach-tegra, since that's the most closely Tegra-related directory. Hiroshi, This driver attempts to cover both Tegra20 and Tegra30. However, there's almost no common code. I think it'd be best as separate tegra20-mc.c and tegra30-mc.c. This patch should include DT binding documentation. That all said, I'd hold off on reposting this until we work out how the MC/GART/SMMU parent-child relationship stuff is worked out; see my immediately previous email.
