[ Upstream commit d77e745613680c54708470402e2b623dcd769681 ]
Currently the regmap_config structure only allows the user to implement single element register read/write using .reg_read/.reg_write callbacks. The regmap_bus already implements bulk counterparts of both, and is being misused as a workaround for the missing bulk read/write callbacks in regmap_config by a couple of drivers. To stop this misuse, add the bulk read/write callbacks to regmap_config and call them from the regmap core code.
This fairly clearly new functionality.
It is, but its needed for 3f42b142ea11 ("serial: max310x: fix IO data corruption in batched operations") which uses this new functionality.
