This branch includes a number of enhancements to core SoC support for
Tegra devices. The major new features are:
* Adds a new CPU-power-gated cpuidle state for Tegra114.
* Adds initial system suspend support for Tegra114, initially supporting
just CPU-power-gating during suspend.
* Adds "LP1" suspend mode support for all of Tegra20/30/114. This mode
both gates CPU power, and places the DRAM into self-refresh mode.
* A new DT-driven PCIe driver to Tegra20/30. The driver is also moved
from arch/arm/mach-tegra/ to drivers/pci/host/.
The PCIe driver work depends on the following tag from Thomas Petazzoni:
git://git.infradead.org/linux-mvebu.git mis-3.12.2
... which is merged into the middle of this pull request.
