Markus Schneider-Pargmann authored
This is a new driver that supports the integrated DisplayPort phy for mediatek SoCs, especially the mt8195. The phy is integrated into the DisplayPort controller and will be created by the mtk-dp driver. This driver expects a struct regmap to be able to work on the same registers 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.

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.
