Add the CPU and PSCI nodes for the NVIDIA Tegra210 platforms so that
all CPUs can be enabled on boot. This assumes that the PSCI firmware
has been loaded during the initial bootstrap on the device before the
kernel starts (which is typically the case for these platforms). The
PSCI firmware version is set to v0.2 which aligns with the current
shipping version for Tegra.
This seems fine, although I'd expect PSCI to be used everywhere on
Tegra, so putting this in tegra210.dtsi would make more sense.
It's fine with me. Although technically, tegra210-smaug ships with
psci-v1.0 and tegra210-jetson-tx1 currently have psci-v0.2. However, I
did test both with the psci version set to v1.0 and the jetson-tx1, did
detect the version automatically and reverted to v0.2 (which is a
feature of psci >= v0.2). For Tegra186 we also have the psci node in the
tegra186-p3310.dtsi.
