+ * As an example, consider this structure:
+ * static const struct udevice_id tegra_i2c_ids[] = {
+ * { .compatible = "nvidia,tegra114-i2c", .data = TYPE_114 },
+ * { .compatible = "nvidia,tegra20-i2c", .data = TYPE_STD },
+ * { .compatible = "nvidia,tegra20-i2c-dvc", .data = TYPE_DVC },
+ * { }
+ * };
+ *
+ * When driver model finds a driver for this it will store the 'data' value
+ * corresponding to the compatible string it matches. This function returns
+ * that value. This allows the driver to handle several variants of a device.
