I have explored that option.

The bit location for clock bit on register are same in case of max77686 
and max77802 but it is different for the max77620.

So until I change it too generic, it will not be possible.
Also if it is require then what about all max77686/max77802 and max77620 
in single file, the way we did for RTC.
We dont need 4 files for the similar driver then.
