+Embedded Memory Controller
+
+Properties:
+- name : Should be emc
+- #address-cells : Should be 1
+- #size-cells : Should be 0
+- compatible : Should contain "nvidia,tegra20-emc".
+- reg : Offset and length of the register set for the device
+- nvidia,use-ram-code : If present, the sub-nodes will be addressed
+  and chosen using the ramcode board selector. If omitted, only one
+  set of tables can be present and said tables will be used
+  irrespective of ram-code configuration.
+
+Child device nodes describe the memory settings for different configurations and clock rates.
+
+Example:
+
+       emc@7000f400 {
+               #address-cells = < 1 >;
+               #size-cells = < 0 >;
+               compatible = "nvidia,tegra20-emc";
+               reg = <0x7000f4000 0x200>;
