Revert "drm/sun4i: Handle DRM_BUS_FLAG_PIXDATA_*EDGE" This reverts commit 2c17a4368aad2b88b68e4390c819e226cf320f70. The offending commit triggers a run-time fault when accessing the panel element of the sun4i_tcon structure when no such panel is attached. It was apparently assumed in said commit that a panel is always used with the TCON. Although it is often the case, this is not always true. For instance a bridge might be used instead of a panel. This issue was discovered using an A13-OLinuXino, that uses the TCON in RGB mode for a simple DAC-based VGA bridge.
