Hmm.. I can't sure it's no affection. e.g we did have customers reporting cd plug in/out causing jitters when system is busy playing audio or video. Maybe we need to do those tests. Anyway, what's your point to keep sending tuning commands after card is already removed?

Not for sdhci_execute_tuning() it's not. Only one command is sent. Currently we don't even send the CMD13 because we check card detect first.

Why not check card detect > after the first error in esdhc_executing_tuning(). > It is not IMX driver problem. IMX is based on SDHCI driver and it does check card detect for CMD13, but sdhci_execute_tuning not. We may either check CD in sdhci_execute_tuning() or disable tuning for card remove case. Personally i'd like to disable it in core since i really can't see the meaning to keep it for card remove. What's your idea?
