It's supplied by S4 and as such will provide 1.8V to something. So it's quite likely that I picked the wrong regulator in the dtsi and that this is the px supply of the wcnss. Unfortunately I don't have any 8064 device (with wcnss) hooked up and I can't find any schematics :/ Would you mind changing the riva-pil vddpx-supply to &pm8921_lvs7 and give this a spin?
