as the DisplayPort controller. It sets the device data to be the struct
phy so that the DisplayPort controller can easily work with it.

The driver does not have any devicetree bindings because the datasheet
does not list the controller and the phy as distinct units.

The interaction with the controller can be covered by the configure
callback of the phy framework and its displayport parameters.

dt-bindings: phy: List supplies for qcom,edp-phy

We're supposed to list the supplies in the dt bindings but there are
none in the eDP PHY bindings.

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.
