Merge tag 'tegra-for-4.10-arm64-dt-numeric-ids' of git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux into next/dt64
Pull "arm64: tegra: Device tree changes for v4.10-rc1" from Thierry Reding: This adds initial support for Tegra186, the P3310 processor module as well as the P2771 development board. Not much is functional, but there is enough to boot to an initial ramdisk with debug serial output. * tag 'tegra-for-4.10-arm64-dt-numeric-ids' of git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux: arm64: tegra: Add NVIDIA P2771 board support arm64: tegra: Enable PSCI on P3310 arm64: tegra: Add NVIDIA P3310 processor module support arm64: tegra: Add GPIO controllers on Tegra186 arm64: tegra: Add SDHCI controllers on Tegra186 arm64: tegra: Add I2C controllers on Tegra186 arm64: tegra: Add serial ports on Tegra186 arm64: tegra: Add CPU nodes for Tegra186 arm64: tegra: Add Tegra186 support
