- Add max_register field to struct regmap_config for debugfs
- Use devm_regmap_init_i2c() to register regmap instaad of regmap_init_i2c()
- Fix typo and remove unnecessary code
- Set irq domain for MAX77693 interrupts regardless of max77693->irq

v3
- Add support irq domain for MAX77693 interrupts
- Apply regmap for i2c

v2
- with comments from Mark
- use devm_kzalloc rather than kzalloc
