3 | Required properties: | ||
4 | - compatible : "nvidia,tegra30-mc" | ||
5 | - reg : Should contain 4 register ranges(address and length); see the | ||
6 | example below. Note that the MC registers are interleaved with the | ||
7 | SMMU registers, and hence must be represented as multiple ranges. | ||
8 | - interrupts : Should contain MC General interrupt. | ||
