A while back, Olof produced a couple of patches to add /generic/ support to deal with power and reset controls for SDIO WIFI cards. Patches were posted to linux-arm-kernel and other places around January time this year. No real conclusion came out of it, and it kind of died. The point here is that this is not an OMAP problem. We have this very same problem on different platforms and different SoCs. Why should we have N different solutions to the same problem. Why can't we have one solution to fix this issue, rather than having every host driver implement some different solution to what's a common problem. If everyone is going to run away from generic problems and continue inventing their own private solutions to generic problems, the kernel is just going to become severely bloated and unmaintainable... Please, sort out generic problems with generic solutions. -- FTTC broadband for 0.8mile line: now at 9.7Mbps down 460kbps up... slowly improving, and getting towards what was expected from it. -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
