By setting enable_reg, enable_mask, enable_val and disable_val, we can use the regulator_enable/disable/is_enabled_regmap helpers. With this change, then regB field can be removed from struct max77650_regulator_desc.
Signed-off-by: Axel Lin <axel....@ingics.com> --- Hi Bartosz, I don't have this h/w, please help to review and test it. I think the only difference is the is_enabled checking: Before the patch, it returns en != MAX77650_REGULATOR_DISABLED; After the patch, it returns en == MAX77650_REGULATOR_ENABLED I'm not sure if this difference does matter or not.
