The idea here is that the compatible string must either be "nvidia,tegra124-vic" if the board is a Tegra124 chip. If it's not, the board must be a Tegra132 (though we probably should add Tegra210 here too) it must be "nvidia,tegra132-vic", "nvidia,tegra124-vic" to indicate that while the hardware is compatible with the Tegra124 VIC (and thus can use the same driver and we don't need to update the compatible list in the driver), it is actually the Tegra132 version in case the driver needs to apply some quirks. Other Tegra bindings use the same system. > > Thanks > Emil Thanks, Mikko -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
