[3/3] drm/i915: Add "panel orientation" property to the panel connector

Commit Message

Hans de Goede Sept. 8, 2017, 11:54 a.m. UTC

For now this is always set to DRM_MODE_PANEL_ORIENTATION_UNKNOWN
unless there is a dmi based quirk overriding the value.

In the future we should probably provide an initial value based on
the VBT (at least for some panel types).
