Merge tag 'tegra-for-4.5-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux into late/tegra
ARM: tegra: Core SoC changes for v4.5-rc1 The big thing here is Tegra210 support, which is really only the Kconfig symbol. Other than that there's a few miscellaneous fixes. * tag 'tegra-for-4.5-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux: 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 Signed-off-by: Olof Johansson <olof@lixom.net>
