The bulk of these changes add memory controller nodes for Tegra30,
Tegra114 and Tegra124. The memory controller implements an IOMMU that
the display controllers are attached to. This allows them to scan out
physically non-contiguous framebuffers and removes one of the primary
users of CMA.
The only other change adds a new MIPI pad control bank to the pin
controller on Tegra124. The corresponding driver patch for this went
into v3.18 as:
3ccc11f6b8 pinctrl: tegra: Add MIPI pad control
