Merge branch 'tegra/soc' into next/soc
* tegra/soc:
arm/tegra: Compile tegra_dt_init_irq only when CONFIG_OF
arm/tegra: Make MACH_TEGRA_DT depend on ARCH_TEGRA_2x_SOC
arm/tegra: Delete tegra_init_clock()
arm/tegra: Fix section mismatch errors in tegra30 pinmux
arm/tegra: Fix section mismatch errors in tegra20 pinmux
arm/tegra: refresh defconfig for tegra30
arm/tegra: add support for tegra30 based board cardhu
arm/tegra: implement support for tegra30
arm/tegra: pinmux tables and definitions for tegra30
arm/tegra: add new fields to struct tegra_pingroup_desc
arm/tegra: prepare pinmux code for multiple tegra variants
arm/tegra: rename tegra20 pinmux files
arm/tegra: generalize L2 cache initialization
arm/tegra: use PMC reset
arm/tegra: rename board-dt.c to board-dt-tegra20.c
arm/tegra: prepare early init for multiple tegra variants
arm/tegra: don't export clk_measure_input_freq
arm/tegra: prepare clock code for multiple tegra variants
arm/tegra: cleanup tegra20 support
arm/tegra: clk_get should not be fatal
