Tegra186: platform support for Tegra "T186" SoC
Tegra186 is the newest SoC in the Tegra family which consists
of two CPU clusters - Denver and A57. The Denver cluster hosts
two next gen Denver15 CPUs while the A57 cluster hosts four ARM
Cortex-A57 CPUs. Unlike previous Tegra generations, all the six
cores on this SoC would be available to the system at the same
time and individual clusters can be powered down to conserve
power.
