Merge tag 'armsoc-tegra' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC support for Tegra platforms from Olof Johansson: "Here's a single-SoC topic branch that we've staged separately. Mainly because it was hard to sort the branch contents in a way that fit our existing branches due to some refactorings. The code has been in -next for quite a while, but we staged it in arm-soc a bit late, which is why we've kept it separate from the other updates and are sending it separately here" * tag 'armsoc-tegra' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: arm64: tegra: Add NVIDIA Jetson TX1 Developer Kit support arm64: tegra: Add NVIDIA P2597 I/O board support arm64: tegra: Add NVIDIA Jetson TX1 support arm64: tegra: Add NVIDIA P2571 board support arm64: tegra: Add NVIDIA P2371 board support arm64: tegra: Add NVIDIA P2595 I/O board support arm64: tegra: Add NVIDIA P2530 main board support arm64: tegra: Add Tegra210 support arm64: tegra: Add NVIDIA Tegra132 Norrin support arm64: tegra: Add Tegra132 support ARM: tegra: select USB_ULPI from EHCI rather than platform ARM: tegra: Ensure entire dcache is flushed on entering LP0/1 amba: Hide TEGRA_AHB symbol soc/tegra: Add Tegra210 support soc/tegra: Provide per-SoC Kconfig symbols
