I think DDC clock is misnamed and according to DW HDMI binding should be named ISFR (clock for special function registers). I did few test tests when writing U-Boot driver and it has to be enabled all the time for driver to work correctly. I did few additional tests few days back - if only DDC clock is enabled and PLL video/HDMI clock disabled, DW HDMI registers are accessible. I guess DDC clock in your case is not needed because controller is already configured correctly. Best regards, Jernej

Looks good. I assume you've tested this? It does continue to work with the bus and DDC clocks disabled, right? Thanks ChenYu
