[PATCH 0/2] drm: Make i915 check for panel orient quirks on eDP and add one such quirk

[Hans de Goede]

Hi All,

This series fixes (works around) the gpd win 2's eDP panel being a
portait mode panel being used in a landscape case (clamshell model).

I plan to merge the i915 bit through dinq and the actual quirk through
drm-misc. These 2 are related in the sense that the quirk will not do
anything without the i915 bits and the i915 bits only actually do anything
once at least 1 quirk entry for an eDP panel is present. But they can be
merged independently.

Regards,

Hans

[PATCH 1/2] drm/i915: Check for panel orientation quirks on eDP panels

[Hans de Goede]

So far we have only been calling
drm_connector_init_panel_orientation_property(), which checks for
panel orientation quirks in the drm_panel_orientation_quirks.c file,
for DSI panels as so far only devices with DSI panels have had panels
which are not mounted up right.

The new GPD win2 device uses a portrait screen in a landscape case,
so now we've a device with an eDP panel which needs the panel-orientation
property to let the fbcon code and userspace know that the image needs to
be fixed-up.

This commit makes intel_edp_init_connector() call
drm_connector_init_panel_orientation_property() so that the property
gets added.

[PATCH 2/2] drm: panel-orientation-quirks: Add quirk for GPD win2

[Hans de Goede]

GPD has done it again, make a nice device (good), use way too generic
DMI strings (bad) and use a portrait screen rotated 90 degrees (ugly).

Because of the too generic DMI strings this entry is also doing bios-date
matching, so the gpd_win2 data struct may very well need to be updated
with some extra bios-dates in the future.

Off-topic/meta:

I got a number of bounces for all the @linux.intel.com addresses,
but according to MAINTAINERS those are still the one to use ?

Hans

Can I get a review / acked-by for these 2 trivial patches, please ?

So that I can push 1 to dinq and the other to drm-misc/next .

Regards,

Hans
