I worked mainly with MX25/35 back then, and a little bit with MX51. IIRC I only had an SDIO card for which no Linux drivers were available, so I only could test that the card was detected :( > That means, the subtle difference between mx_sdhci and sdhci to get SDIO > IRQS to work on sdhci with iMX53 has yet to be found. Yup. Try 'git log --follow sdhci-esdhc-imx.c' to find people who worked with MX53 or SDIO using that driver.
