Thanks Lee for review.
I will take care of most of stuff on next version of patch.

However, I have some query form your comment.

I don't want people hand-rolling this stuff.  If it's useful to you,
it's useful to others, so great a generic implementation that lives in
the kernel headers directory.

yaah, generic implementation possible. I can put the new defines in the 
mfd/core.h.

This will be similar to
+/* Define mfd cells with name and resource */
+#define DEFINE_MFD_CELL_NAME_RESOURCE(_name, _res)             \
+       {                                                       \
+               .name = (_name),                                \
+               .num_resources = ARRAY_SIZE((res)),             \
+               .resources = (_res),                            \
+       }
+
+/* Define mfd cells with name */
+#define DEFINE_MFD_CELL_NAME(_name)                            \
+       {                                                       \
+               .name = (_name),                                \
+       }
+

This will be separate patch and should be applied before this series.
Does it look fine?

This is not acceptable.  EITHER use DT OR MFD methods of registering
devices, do not mix the two.

You mean I need to either provide the i2c_device_id table or the 
of_device_id table, not both?
Do I need to protect it by CONFIG_OF?

This only support the DT method of registration. So do I need to remove 
i2c_device_id?
