Hi As described in patch 3, re-tuning for HS400 has to be done in HS200 mode, but there is no support for that, so re-tuning needs to be disabled until support is added. I have some patches for that which I will send in the next day or two. Adrian Hunter (3): mmc: sdhci: Tuning should not change max_blk_count mmc: sdhci: Add out_unlock to sdhci_execute_tuning mmc: sdhci: Disable re-tuning for HS400 Regards Adrian -- To unsubscribe from this list: send the line "unsubscribe linux-mmc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
