Does the LS1012ARDB support SD UHS-I?

Iam trying to check the performance of the SD card on the LS1012ARDB, using a Sandisk Extreme Pro UHS-I sd card.


When I check the AUTOCERR_SYSCTL2 register of the esdhc1 I see the UHSM field is set to SDR12 (with and without data transfer):


root@OpenWrt:/mnt# devmem 0x156003c


The manual says that the LS1012A itself supports SDR104. My question is, does the RDB supports UHS-I mode? if yes how to switch the Linux driver to use it?


Thank you,
