Looking at the downstream regulator definition lvs7 is identified as
"pll_vdd" - which I believe is what Qualcomm abbreviates as "px". 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?
