1. How does this relates to regulator driver? The
drivers/regulator/88pm800.c defines constraints for regulator which may
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).
