How does this relates to regulator driver? The drivers/regulator/88pm800.c defines constraints for regulator which may be contradictory. 2. This looks like a job for regulator driver, not MFD. Then you could use standard regulator bindings (setting maximum current to 6A would change the regulator to different mode).
