Perhaps it is better to create some generic binding for that? There may
be other drivers/components that have the same strange combinations and
need a similar binding to use for regmap.

We could use something like an "endian" property with "big", "little"
and "native" which is then parsed by some function of the regmap
framework. It could directly fill those information into the
struct regmap_config.

Thanks,

Markus
