Looking at the Linux driver and existing device trees, we can see that two supplies are expected: - vdda-0p9-supply - vdda-1p2-supply Let's list them both in the bindings. Note that the datasheet for sc7280 doesn't describe these supplies very verbosely. For the 0p9 supply, for instance, it says "Power for eDP 0.9 V circuits". This this is obvious from the property name, we don't bother cluttering the bindings with a description.

Looking at the driver in Linux, I can see that there seem to be two relevant supplies: "vdda-phy" and "vdda-pll". Let's add those to the bindings. NOTE: from looking at the Qualcomm datasheet for sc7280, it's not immediately clear how to figure out how to fill in these supplies. The only two eDP related supplies are simply described as "power for eDP 0.9V circuits" and "power for eDP 1.2V circuits". From guessing and from comparing how a similar PHY is hooked up on other similar Qualcomm boards, I'll make the educated guess that the 1.2V supply goes to "vdda-phy" and the 0.9V supply goes to "vdda-pll" and I'll use that in the example here.
