   irrespective of ram-code configuration.
 - interrupts : Should contain EMC General interrupt.
 - clocks : Should contain EMC clock.
+- nvidia,memory-controller : Phandle of the Memory Controller node.
+- #interconnect-cells : Should be 0.
+- operating-points-v2: See ../bindings/opp/opp.txt for details.
+
+For each opp entry in 'operating-points-v2' table:
+- opp-supported-hw: One bitfield indicating SoC process ID mask
+
+       A bitwise AND is performed against this value and if any bit
+       matches, the OPP gets enabled.
+
+Optional properties:
+- core-supply: Phandle of voltage regulator of the SoC "core" power domain.
 
 Child device nodes describe the memory settings for different configurations and clock rates.
