Hi,
Hi,
Second version of my series, no major changes: * rephrased warnings * collected some tags * rebased to mmc/mmc-next as of today Eric wanted to tested these patches soonish. Thanks to Marc for testing the first three already.
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 ? Arnaud
