so far we have only been able to achieve UHS speeds on devices based on the
rk808 pmic (I had sucess on veyron and popmetal). The act8846-based boards
seem to have some issue when trying to do the switch to 1.8V, resulting in
mmc errors and the mmc-core switching back to 3.3V.
I think this might be caused by a bug in the act8846 driver or some dts
mistake. But so far nobody had the time and enthusiasm to investigate :-)
