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.

Hey Mark, sorry for hijacking the thread a bit. regmap.h seems to have comprehensive API documentation, but there's very little in terms of higher level documentation that I could find. Is there any?
I've been toying with the idea of adding a regmap based interface for accessing Display Port DPCD registers, with caching, and regmap seems like it's got the kitchen sink but I find it a bit difficult to navigate...
BR, Jani.
