This patch doesn't fully handle the device tree binding. There are two
alternatives:
two-level:
emc {
...
emc-table at 190000 {
compatible = "nvidia,tegra20-emc-table";
...
};
emc-table at 380000 {
compatible = "nvidia,tegra20-emc-table";
...
};
};
three-level:
emc {
...
nvidia,use-ram-code;
emc-tables {
nvidia,ram-code = <0>;
emc-table at 190000 {
compatible = "nvidia,tegra20-emc-table";
...
};
emc-table at 380000 {
compatible = "nvidia,tegra20-emc-table";
...
};
};
emc-tables {
nvidia,ram-code = <1>;
emc-table at 190000 {
compatible = "nvidia,tegra20-emc-table";
...
};
emc-table at 380000 {
compatible = "nvidia,tegra20-emc-table";
...
};
};
};
Even if we don't fully implement support for both, we should detect the
unsupported and flag an explicit error. But, it's pretty easy to support
the other format.
BTW, does:
+ node = fdtdec_next_compatible(blob, node,
+ COMPAT_NVIDIA_TEGRA20_EMC_TABLE);
limit itself to searching child nodes?
