1 NVIDIA Tegra20 MC(Memory Controller)
4 - compatible : "nvidia,tegra20-mc-gart"
5 - reg : Should contain 2 register ranges: physical base address and length of
6 the controller's registers and the GART aperture respectively.
7 - clocks: Must contain an entry for each entry in clock-names.
8 See ../clocks/clock-bindings.txt for details.
9 - clock-names: Must include the following entries:
10 - mc: the module's clock input
11 - interrupts : Should contain MC General interrupt.
12 - #reset-cells : Should be 1. This cell represents memory client module ID.
13 The assignments may be found in header file <dt-bindings/memory/tegra20-mc.h>
14 or in the TRM documentation.
15 - #iommu-cells: Should be 0. This cell represents the number of cells in an
16 IOMMU specifier needed to encode an address. GART supports only a single
17 address space that is shared by all devices, therefore no additional
18 information needed for the address encoding.
