A few notes: * Similar to hdmi-connector, it has hpd-gpios as an optional property, as the HPD could also be handled by, e.g., the DP bridge. * dp-pwr-supply, which provides 3.3V on DP_PWR pin, is optional, as it is not strictly required: standard DP cables do not even have the pin connected. * Connector type. Full size and mini connectors are identical except for the connector size and form, so I believe there is no functional need for this property. But similar to 'label' property, it might be used to present information about the connector to the userspace. * No eDP. There's really no "eDP connector", as it's always a custom made connection between the DP and the DP panel, although the eDP spec does offer a few suggested pin setups. So possibly there is no need for edp-connector binding, but even if there is, I don't want to guess what it could look like, and could it be part of the dp-connector binding. * No DP++. I'm not familiar with DP++. DP++ might need an i2c bus added to the bindings.
