No. NVIDIA's downstream kernels use SKU (along with other) information to determine clock/voltage limits, etc. However, we don't have any DVFS code or aggressive clock settings in mainline at present, so unknown SKUS won't be a problem. The same goes for mainline U-Boot. Still, it would be nice to squash the warning for you. Peter, any chance you could look up the appropriate speedo IDs and fill in a case for this SKU in tegra30_speedo.c? Is it possible to fill in all known SKUs? -- 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
