During commit "88bc4178568b8e0331143cc0616640ab72f0cba1" DRM_BUS_FLAG_*
Please use same commit referencing approach as for "Fixes" tag.
macros have been changed to avoid ambiguity but just because of this ambiguity previous DRM_BUS_FLAG_PIXDATA_(POS/NEG)EDGE were used meaning _SAMPLE_ not _DRIVE_. This lead to DLCK inversion, so let's swap DCLK phase to fix it.
Add Fixes tag here.
Best regards, Jernej
