For many drivers which will support rich endianness of Devices need define DT properties by itself with the binding support. The regmap core has already support endianness of the following case: Index Device DT properties needed ------------------------------------------ 1 BE 'big-endian' 2 LE 'little-endian' Please see the regmap binding for more detail information of the endianness support.
