[PATCH v9 51/61] drm/tests: bridge: Set supported HDMI version
From: Cristian Ciocaltea
Date: Wed Jul 22 2026 - 21:48:36 EST
Bridges using DRM_BRIDGE_OP_HDMI are now expected to also provide a
supported HDMI version. This is not yet enforced, but will become
mandatory once the migration to the new HDMI connector initialization API
is completed.
Advertise HDMI 1.4 as the default for the test bridges, since that is
the highest version that does not require additional initialization
data. This also avoids implying support for HDMI capabilities they do
not currently model.
