Checking the 1.8 V constraint then fails with -EINVAL, and the RPM regulator driver aborts the probe of all PM8994 regulators. Drop the constraints, like apq8096-db820c, which describes LVS1/LVS2 without them. Keep the node, so that the SLPI still gets its px-supply. Describing vdd_lvs1_2-supply as S4, as done on other MSM8996 boards, would also work, but it would only serve the constraint, which has nothing to enforce on a switch. Tested on OnePlus 3T with the msm8996-mainline kernel based on v6.19.5.
