We're supposed to list the supplies in the dt bindings but there are none in the DP controller bindings. 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. Signed-off-by:

Thomas Zimmermann authoredImplement DRM's aperture helpers under video/ for sharing with other sub-systems. Remove DRM-isms from the interface. The helpers track the ownership of framebuffer apertures and provide hand-over from firmware, such as EFI and VESA, to native graphics drivers. Other subsystems, such as fbdev and vfio, also have to maintain ownership of framebuffer apertures. Moving DRM's aperture helpers to a more public location allows all subsystems to interact with each other and share a common implementation. The aperture helpers are selected by the various firmware drivers within DRM and fbdev, and the VGA text-console driver. The original DRM interface is kept in place for use by DRM drivers. v3: * prefix all interfaces with aperture_ (Javier) * rework and simplify documentation (Javier) * rename struct dev_aperture to struct aperture_range * rebase onto latest DRM * update MAINTAINERS entry Signed-off-by:
