Subject: [PATCH 43/69] DSS2: Swap field 0 and field 1 registers
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.
