+The only case where enabling fieldmode automatically seems reasonable

+The values for the registers which have alternate values for each field

+is the even field or the bottom field, field 1 is the odd field or the
+top field. So simply swap the register values.

+Subject: [PATCH] DSS2: add sysfs entry for seting the rotate type
+
+This can help in utilizing VRAM memory better. Since with VRFB rotation
+we waste a lot of physical memory due to the VRFB HW design, provide the
+possibility to turn it off and free the extra memory for the use by other
+planes for example.
