dw_hdmi sets a pixel repetition factor of 1 for VICs 10-15, 25-30 and 35-38. However, DRM uses their native resolutions in its timing information. For example, VIC 14 can be 1440x480 with no repetition, or 720x480 with one pixel repetition. As DRM uses 1440 pixels per line for this video mode, we need no pixel repetition.
In any case, pixel repetition appears broken in dw_hdmi.
