-Subject: [PATCH] vc4/drm: Fix source offsets with DRM_FORMAT_P030
-
-Spec says: bits [31:4] of the given address should point to
-the 128-bit word containing the desired starting pixel,
-and bits[3:0] should be between 0 and 11, indicating which
-of the 12-pixels in that 128-bit word is the first pixel to be used
