Does the iMX6q Sabre-lite platform support SDIO 3.0 UHS mode

IMX6Q Sabre-lite is booted with kernel 4.9.11 for interfacing an SDIO based WIFI cardsupporting SDIO 3.0. It is detecting the WiFI card as Normal high speed SD card. It is not detecting as UHS SDIO 3.0 card. host supplies 50MHz clock to WiFi card.

Does the iMX6q Sabre-lite platform support SDIO 3.0 UHS mode devices?

Is there any changes to be done in dtb file for this requirement? Any patches available?

Regards,

Hi,

No the SabreLite doesn't support SDIO3.0 operations since it requires to switch NVCC_SDx to 1.8V whereas the design fixes it to 3.3V.
