The power management controller on Tegra186 has changed in backwards-
incompatible ways with respect to earlier generations. This implements a
new driver that supports inversion of the PMU interrupt as well as the
"recovery", "bootloader" and "forced-recovery" reboot commands.

IIUC, Tegra186 implements PSCI v1.0 and it always takes above path.
So what other platforms does this driver support ? The name is
pmc-tegra186.c, hence the confusion.
