How did you test the patch?
Hi Shawn, The tests was done simpling inserting and removing the SD card, since before no parameters were passed to the imx53_add_sdhci_esdhc_imx and the controller was able to detect the card via software. When setting up the iomux (CD) pin and passing it to the imx53_add_sdhci_esdhc_imx function, it should be able to start detecting the card using the pin instead. the same test was made for [PATCH1/2]. regards, Andre

The CD is working in the exactly same way before you patch. If you check function esdhc_pltfm_init of sdhci-esdhc-imx driver, you will find the following. /* i.MX5x has issues to be researched */ if (!cpu_is_mx25() && !cpu_is_mx35()) goto not_supported; CD gpio interrupt only gets supported on mx25 and mx35 currently, and mx5 CD works with flag SDHCI_QUIRK_BROKEN_CARD_DETECTION set, in which case a very expensive method is being used to poll card present by sdhci driver.
