Hi Thierry,
Will you take a look at this failure and prepare a follow-up patch? This
came already from soc tree.
Best regards,
Krzysztof

I thought I had sent out a reply earlier, but that doesn't seem to have
made it through.
I sent out a patch earlier that fixes this by adding a stub for
tegra_mc_probe_device() if TEGRA_MC is not set. I think that's a bit
better than adding a dependency on TEGRA_MC from the ARM_SMMU driver
because somebody may want to build the ARM_SMMU driver on non-Tegra
configurations.
Another alternative would've been to add another Kconfig symbol for the
Tegra ARM SMMU implementation, but that would've been more intrusive and
would've prevented the Tegra code from getting broader build coverage.
Let me know what you think about the fix and if you want a different
solution than the stub.
Thierry

Stub works for me, thanks!
