Merge tag 'tegra-for-3.19-dt' of git://git./linux/kernel/git/tegra/linux into next/dt2

Pull "ARM: tegra: Device tree changes for v3.19" from Thierry Reding:

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:
