I assume you would than NAK someone trying to get support for their Nexus 9 Tablet using a Tegra K1.  It appears the shipping code for that device didn’t use PSCI (again guessing because it wasn’t available at the time).

If so, I find this counter to the Linux kernel communities normal desire to support the most hardware platforms.
