Tegra 114 is different with other Tegra SoC chips. It using ARM Cortex-A15
as CPU core and a enhanced flow controller for CPU power control. So
we need to skip some code that was for Contex-A9 and some other support
code that was for other Tegra SoC chips. Then adding the proper power up
and hot plug control for Tegra114.

Joseph Lo (6):
  ARM: tegra: add an assembly marco to check Tegra SoC ID
  ARM: tegra: skip SCU and PL310 code when CPU is not Cortex-A9
  ARM: tegra: make tegra_resume can work for Tegra114
  ARM: tegra114: add power up sequence for warm boot CPU
  clk: tegra114: implement wait_for_reset and disable_clock for
    tegra_cpu_car_ops
  ARM: tegra114: add CPU hotplug support
