Since v4.7 the dma initialization requires that there is a device tree property for "rx" and "tx" channels which is not provided by the pdata-quirks initialization.
By conversion of the mmc3 setup to device tree this will finally allows to remove the OpenPandora wlan specific omap3 data-quirks.

I guess this should be in the range of 2.7V-3.6V.
Well, it is a gpio which enables some LDO inside the wifi chip. We do not really know the voltage it produces and it does not matter. The gpio voltage is 1.8V.
Basically we use a fixed-regulator to "translate" a regulator into a control gpio because the mmc interface wants to see a vmmc-supply.
