[PATCH v3 0/1] drm/i915/display: Add quirk to force backlight type on some TUXEDO devices

From: Werner Sembach

Date: Tue Aug 04 2026 - 16:03:33 EST


Since the proposed general fix, fixed the backlight on TUXEDO devices but
broke it on toher ones:
- https://gitlab.freedesktop.org/drm/i915/kernel/-/work_items/15679#note_3581777
- https://lore.kernel.org/all/20260515155340.1000997-1-suraj.kandpal@xxxxxxxxx/
I'm back here again proposing the fix via quirk.

I therefore rebased
https://lore.kernel.org/all/20260121223944.1104951-1-wse@xxxxxxxxxxxxxxxxxxx/
to cleanly apply on current drm-tip.

V1-V2: Switch from dmis trings to PCI-IDs
V2-V3: Rebase onto current drm-tip
