If both the AHB and SMMU driver are core_initcall, there's no guarantee at all re: which order they'll get probed in. Deferred probe won't help here, since I don't think it's guaranteed to be repeated, so if the probe order is: 1) SMMU (fails since AHB isn't available) 2) AHB ... then the SMMU might not get probed until /much/ later; probably after devices that are affected by the SMMU are probed. However, it all works out if the probe order just accidentally happens to be: 1) AHB 2) SMMU. So, this really doesn't look like a viable solution. -- 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
