 	 * The pitch and offset order is dictated by the fourcc,
 	 * e.g. NV12 (http://fourcc.org/yuv.php#NV12) is described as:
+	 *
 	 *   YUV 4:2:0 image with a plane of 8 bit Y samples
 	 *   followed by an interleaved U/V plane containing
+	 *   8 bit 2x2 subsampled colour difference samples.
-	 *   8 bit 2x2 subsampled colour difference samples.
+	 *
+	 * So it would consist of Y as offsets[0] and UV as
+	 * offsets[1].  Note that offsets[0] will generally
+	 * be 0 (but this is not required).
+	 *
+	 * To accommodate tiled, compressed, etc formats, a per-plane
+	 * modifier can be specified.  The default value of zero
 	 * indicates "native" format as specified by the fourcc.
-	 * So it would consist of Y as offset[0] and UV as
+	 * Vendor specific modifier token.  This allows, for example,
-	 * offeset[1].  Note that offset[0] will generally
+	 * different tiling/swizzling pattern on different planes.
-	 * be 0.
+	 * See discussion above of DRM_FORMAT_MOD_xxx.
