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.
