This adds the plumbing for reading panel rotation from the devicetree
and sets up adding a panel property for the panel orientation on
Mediatek SoCs when a rotation is present.
v6 changes:
-added enum declaration to drm_panel.h header
v5 changes:
-rebased
v4 changes:
-fixed some changes made to the i915 driver
-clarified comments on of orientation helper
v3 changes:
-changed from attach/detach callbacks to directly setting fixed panel
values in drm_panel_attach
-removed update to Documentation
-added separate function for quirked panel orientation property init
v2 changes:
fixed build errors in i915
Derek Basehore (4):
drm/panel: Add helper for reading DT rotation
drm/panel: set display info in panel attach
drm/connector: Split out orientation quirk detection
drm/mtk: add panel orientation property

Devicetree systems can set panel orientation via a panel binding, but
there's no way, as is, to propagate this setting to the connector,
where the property need to be added.
To address this, this patch sets orientation, as well as other fixed
values for the panel, in the drm_panel_attach function. These values
are stored from probe in the drm_panel struct.

split the drm_connector_init_panel_orientation_property into two
functions. One for platforms without the need for quirks, and the
other for platforms that need quirks.

if the panel orientation (connector.display_info.panel_orientation) is
not DRM_MODE_PANEL_ORIENTATION_UNKNOWN.

not DRM_MODE_PANEL_ORIENTATION_UNKNOWN.
