Merge tag 'tegra-soc2' of git://git.kernel.org/pub/scm/linux/kernel/git/olof/tegra into tegra/soc2
From: Olof Johansson <olof@lixom.net> Tegra 30 SMP support I did this as a separate topic branch because it depends on both the soc and the soc-drivers branch, so it brings both of those in as a base. This branch contains work to enable SMP support on Tegra30 and reworks some of the SMP bringup for T20 as well. It also contains a device tree patch that builds on top of the SMP/clock changes in the rest of the branch, so it made more sense to apply it here than deal with the merge conflicts back and forth. * tag 'tegra-soc2' of git://git.kernel.org/pub/scm/linux/kernel/git/olof/tegra: ARM: dt: Explicitly configure all serial ports on Tegra Cardhu ARM: tegra: support for secondary cores on Tegra30 ARM: tegra: support for Tegra30 CPU powerdomains ARM: tegra: add support for Tegra30 powerdomains ARM: tegra: export tegra_powergate_is_powered() ARM: tegra: prepare powergate.c for multiple variants ARM: tegra: rework Tegra secondary CPU core bringup ARM: tegra: functions to access the flowcontroller ARM: tegra: initialize Tegra chipid early ARM: tegra: export Tegra chipid ARM: tegra: cleanup use of chipid register Signed-off-by: Arnd Bergmann <arnd@arndb.de>
