With coming Qualcomm Soundwire v2.0, several registers were moved and changed, thus a different register layout will have to be supported. Prepare for this by: 1. Renaming few register defines to indicate v1.3 (earliest supported) version, 2. Add a simple table for mapping register to its offset, 3. Change the code to use the mapping table. Since only few registers differ, this solution seems easier then switching to regmap fields. Signed-off-by: Krzysztof Kozlowski Reviewed-by: Konrad Dybcio --- Changes since v1: 1.
