+MIME-Version: 1.0
+Content-Type: text/plain; charset=utf-8
+Content-Transfer-Encoding: 8bit
+
+When using fieldmode each field is basically a separate picture so the
+vertical filter should start at phase 0 for both fields.

+Content-Type: text/plain; charset=utf-8
+Content-Transfer-Encoding: 8bit
+
+The only case where enabling fieldmode automatically seems reasonable
+is when source and destination heights are equal. Some kind of user
+controllable knob should be added so the user could enable field mode
+when the source is interlaced.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=utf-8
+Content-Transfer-Encoding: 8bit
+
+The values for the registers which have alternate values for each field
+were reveresed to what the hardware expects. For the hardware field 0
+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.
