+title: NVIDIA Tegra186 (and later) SoC Memory Controller
+
+maintainers:
+ - Jon Hunter <jonathanh@nvidia.com>

+
+description: |
+ The NVIDIA Tegra186 SoC features a 128 bit memory controller that is split
+ into four 32 bit channels to support LPDDR4 with x16 subpartitions. The MC
+ handles memory requests for 40-bit virtual addresses from internal clients
+ and arbitrates among them to allocate memory bandwidth.
+
+ Up to 15 GiB of physical memory can be supported. Security features such as
+ encryption of traffic to and from DRAM via general security apertures are
+ available for video and other secure applications, as well as DRAM ECC for
+ automotive safety applications (single bit error correction and double bit
+ error detection).

+ description:
+ The bulk of the work involved in controlling the external memory
+ controller on NVIDIA Tegra186 and later is performed on the BPMP. This
+ coprocessor exposes the EMC clock that is used to set the frequency at
+ which the external memory is clocked and a remote procedure call that
+ can be used to obtain the set of available frequencies.
