That kernel isn’t officially supported, you’ll probably have to adapt the tegra18_defconfig from the supported R27.1 kernel. In cases where drivers have basically the same interface no change would be required, but some features may not even exist on 4.12-rc5 (that’s the most recent at this time on kernel.org), and others may need edits.
