As I have said several times now drivers implementing their own regmap operations should use the reg_read() and reg_write() operations in regmap_config when allocating their regmap unless they're doing something unusual. There are a few cases where it makes sense but nothing I've seen here makes it look like this is one of them. Most of the current users don't fit. Please, just implement a normal driver using a normal regmap_config as I've repeatedly said you should if you don't want to provide something generic.
