with v6.9 and later there is no output on the BananaPI HDMI connector.I have bisected the issue to the following commit: 358e76fd613a ("drm/sun4i: hdmi: Consolidate atomic_check and mode_valid")With this patch, sun4i_hdmi_connector_clock_valid() is occasionally called with clock=0, causing the function to return MODE_NOCLOCK. In the old sun4i_hdmi_mode_valid() before the patch, mode->clock is always!=0, maybe that gives someone a hint.
