So maybe we want something like ... - compatible : Should contain one of the following: - "nvidia,tegra20-ahbdma": for Tegra20 - "nvidia,tegra30-ahbdma", "nvidia,tegra20-ahbdma": for Tegra30 Please note that even thought the driver may only currently define the compatible string "nvidia,tegra20-ahbdma", adding "nvidia,tegra30-ahbdma" in the dts for Tegra30 is good practice if a bug/difference is found later on.
