Hi Krzysztof,
Thanks for review.
I will fix most of your comment on my next patch.

Answering to some of comment/query.

I ran checkpatch before I sent.

There is some parameter difference for MAX77620 and MAX20024. I have 
only one structure for it and changing tun time so I have not define 
this structure as constant.
Now API needs const type structure and hence casting it.

However, I have  define different structure for MAX77620 and MAX20024 
which are const type and hence no need to explicitly casting here. This 
will be in my next patch.

+static inline int max77620_reg_update(struct device *dev, int sid,
+               unsigned int reg, unsigned int mask, unsigned int val)
+{
+       struct max77620_chip *chip = dev_get_drvdata(dev);
+
+       return regmap_update_bits(chip->rmap[sid], reg, mask, val);
+}

If I dont make inline from header then this will complain as unused 
static function on related C compilation if it is not used on C. This 
header included from all sub module driver and they are not using all 
these APIs.

To avoid compilation warning,  I need to use inline here.
