 NVIDIA Tegra20 MC(Memory Controller)
 
 Required properties:
-- compatible : "nvidia,tegra20-mc"
-- reg : Should contain 2 register ranges(address and length); see the
-  example below. Note that the MC registers are interleaved with the
-  GART registers, and hence must be represented as multiple ranges.
+- compatible : "nvidia,tegra20-mc-gart"
+- reg : Should contain 2 register ranges: physical base address and length of
+  the controller's registers and the GART aperture respectively.
+- clocks: Must contain an entry for each entry in clock-names.
+  See ../clocks/clock-bindings.txt for details.
+- clock-names: Must include the following entries:
+  - mc: the module's clock input
 - interrupts : Should contain MC General interrupt.
 - #reset-cells : Should be 1. This cell represents memory client module ID.
   The assignments may be found in header file <dt-bindings/memory/tegra20-mc.h>
   or in the TRM documentation.
+- #iommu-cells: Should be 0. This cell represents the number of cells in an
+  IOMMU specifier needed to encode an address. GART supports only a single
+  address space that is shared by all devices, therefore no additional
+  information needed for the address encoding.
 
 Example:
 	mc: memory-controller@7000f000 {
-		compatible = "nvidia,tegra20-mc";
-		reg = <0x7000f000 0x024

+		clocks = <&tegra_car TEGRA20_CLK_MC>;
