Next time, feel free to cc me. :) I removed the quirk during driver cleanup because, based on my testing, it was no longer needed. I also asked nvidia why the quirk was ever needed (took a while to get a response): Turns out it was left over from hardware errata on a previous product using the same IP block (i.e. Tegra 1), and is no longer required for Tegra 2 (since the block gap interrupt is enabled). So, no, it should not be needed in the upstream driver. The patch from Grant is though. If it's unappetizing for sdhci-wide consumption, we could add suspend/resume hooks for sdhci-tegra only and save/restore it there. -Olof -- To unsubscribe from this list: send the line "unsubscribe linux-mmc" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
