The output however flickers, once link is trained with HBR3. Until commit 8c9006283e4b ("Revert "drm/i915/dp: Reject HBR3 when sink doesn't support TPS4"") such sinks were capped at HBR2 by the TPS4 check which incidentally kept this panel stable. That check was reverted because other panels legitimately need HBR3 without advertising TPS4, and the per-machine QUIRK_EDP_LIMIT_RATE_HBR2 was introduced to handle the affected machines instead. Add the machine to the list of devices that need the QUIRK_EDP_LIMIT_RATE_HBR2.
