USDHC - SDIO on iMX53 vs iMX6

Hi All,

I have an iMX53 and iMX6Q Sabre SD dev boards, both boards were running the same kernel based on 3.11-rc7, with same sdhci core, sdhci-esdhc-imx controller for handling USDHC devices. My WIFI module (SD8797) work on iMX53 (4bit mode) and didn't get any error upon loading the driver but, running it with iMX6 the TIMEOUT bit on INT STATUS register was set when I checked it. The other strange was that if I use different wifi module (atheros), the said module work on iMX6 on 4bit mode.

Any idea, pointers or clue that you can share with me?.

Regards,

john
