H A D | tegra186.dtsi | 3f6eaef9 Sun Dec 22 08:10:34 CST 2019 Thierry Reding <treding@nvidia.com> arm64: tegra: Add external memory controller on Tegra186
Add the external memory controller as a child device of the memory controller on Tegra186. The memory controller really represents the memory subsystem that encompasses both the memory and external memory controllers. The external memory controller uses the BPMP to obtain the list of supported EMC frequencies and set the EMC frequency.
Also set up the dma-ranges property to describe that all memory clients can address up to 40 bits using the memory controller client interface (MCCIF), unless otherwise limited by the DMA engines of the hardware.
