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 caps-based HDMI connector
initialization API is completed.
The RK3066 HDMI TX supports HDMI 1.4a, as described in commit
f84d3d37b7 ("drm: rockchip: introduce rk3066 hdmi"). However, the
driver does not currently enforce a maximum TMDS character rate, it only
filters non-CEA modes and excludes VIC 1 (640x480) via the .mode_valid
callback.
Advertise HDMI 1.4 support for now so that modes exceeding the 340 MHz
TMDS limit are rejected by the core.
