From: Thierry Reding <treding@xxxxxxxxxx> Hi, this set of patches improves the Tegra186 memory controller support and extends it with Tegra194 support. The first three patches add the needed device tree bindings and headers. Patches 4-10 first refactor the driver to make it easier to support multiple SoC generations and finally add EMC frequency scaling support (via debugfs) as well as Tegra194 support. The last three patches enable the memory and external memory controllers in device tree.
