Some notebook systems provide the EDID for the internal panel via the _DDC method in ACPI, instead of or in addition to providing the EDID via DDC on LVDS/eDP. Add a DRM helper to search for an ACP _DDC method under the ACPI namespace for each VGA/3D controller, and return the first EDID successfully retrieved via _DDC. Update the i915, nouveau, and radeon DRM-KMS drivers to fall back to

...individual display output, so there could be an arbitrary number of outputs exposing their EDIDs via _DDC; however, in practice, this has only been implemented so far on systems with a single panel, so the current implementation of drm_get_edid_acpi() walks the outputs listed by each GPU's ACPI _DOD method and returns the first EDID successfully retrieved by any attached _DDC method. It may be necessary in the future to allow for the retrieval of distinct EDIDs for different output devices, but in order to do so, it will first be necessary to develop a way to correlate individual DRM outputs w...
