Has this been tested on imx51 ? By default (even after applying your
patches), the sdhci has quirk SDHCI_QUIRK_BROKEN_CARD_DETECTION set, so
we're polling.
I've been wondering if it was a good idea to configure for everyone sdhc
host card detect pin as gpio 1 1 or gpio 1 8 on imx51, which would mean
no more polling. What do you think ? Would it be working or it's just a
stupid idea ?
